World War I

By: History.com Editors

Updated: August 11, 2023 | Original: October 29, 2009

World War I, also known as the Great War, started in 1914 after the assassination of Archduke Franz Ferdinand of Austria. His murder catapulted into a war across Europe that lasted until 1918. During the four-year conflict, Germany, Austria-Hungary, Bulgaria and the Ottoman Empire (the Central Powers) fought against Great Britain, France, Russia, Italy, Romania, Canada, Japan and the United States (the Allied Powers). Thanks to new military technologies and the horrors of trench warfare, World War I saw unprecedented levels of carnage and destruction. By the time the war was over and the Allied Powers had won, more than 16 million people—soldiers and civilians alike—were dead.

Archduke Franz Ferdinand

Tensions had been brewing throughout Europe—especially in the troubled Balkan region of southeast Europe—for years before World War I actually broke out.

A number of alliances involving European powers, the Ottoman Empire , Russia and other parties had existed for years, but political instability in the Balkans (particularly Bosnia, Serbia and Herzegovina) threatened to destroy these agreements.

The spark that ignited World War I was struck in Sarajevo, Bosnia, where Archduke Franz Ferdinand —heir to the Austro-Hungarian Empire—was shot to death along with his wife, Sophie, by the Serbian nationalist Gavrilo Princip on June 28, 1914. Princip and other nationalists were struggling to end Austro-Hungarian rule over Bosnia and Herzegovina.

The assassination of Franz Ferdinand set off a rapidly escalating chain of events: Austria-Hungary , like many countries around the world, blamed the Serbian government for the attack and hoped to use the incident as justification for settling the question of Serbian nationalism once and for all.

Kaiser Wilhelm II

Because mighty Russia supported Serbia, Austria-Hungary waited to declare war until its leaders received assurance from German leader Kaiser Wilhelm II that Germany would support their cause. Austro-Hungarian leaders feared that a Russian intervention would involve Russia’s ally, France, and possibly Great Britain as well.

On July 5, Kaiser Wilhelm secretly pledged his support, giving Austria-Hungary a so-called carte blanche, or “blank check” assurance of Germany’s backing in the case of war. The Dual Monarchy of Austria-Hungary then sent an ultimatum to Serbia, with such harsh terms as to make it almost impossible to accept.

World War I Begins

Convinced that Austria-Hungary was readying for war, the Serbian government ordered the Serbian army to mobilize and appealed to Russia for assistance. On July 28, Austria-Hungary declared war on Serbia, and the tenuous peace between Europe’s great powers quickly collapsed.

Within a week, Russia, Belgium, France, Great Britain and Serbia had lined up against Austria-Hungary and Germany, and World War I had begun.

The Western Front

According to an aggressive military strategy known as the Schlieffen Plan (named for its mastermind, German Field Marshal Alfred von Schlieffen ), Germany began fighting World War I on two fronts, invading France through neutral Belgium in the west and confronting Russia in the east.

On August 4, 1914, German troops crossed the border into Belgium. In the first battle of World War I, the Germans assaulted the heavily fortified city of Liege , using the most powerful weapons in their arsenal—enormous siege cannons—to capture the city by August 15. The Germans left death and destruction in their wake as they advanced through Belgium toward France, shooting civilians and executing a Belgian priest they had accused of inciting civilian resistance. 

First Battle of the Marne

In the First Battle of the Marne , fought from September 6-9, 1914, French and British forces confronted the invading German army, which had by then penetrated deep into northeastern France, within 30 miles of Paris. The Allied troops checked the German advance and mounted a successful counterattack, driving the Germans back to the north of the Aisne River.

The defeat meant the end of German plans for a quick victory in France. Both sides dug into trenches , and the Western Front was the setting for a hellish war of attrition that would last more than three years.

Particularly long and costly battles in this campaign were fought at Verdun (February-December 1916) and the Battle of the Somme (July-November 1916). German and French troops suffered close to a million casualties in the Battle of Verdun alone.

World War I Books and Art

The bloodshed on the battlefields of the Western Front, and the difficulties its soldiers had for years after the fighting had ended, inspired such works of art as “ All Quiet on the Western Front ” by Erich Maria Remarque and “ In Flanders Fields ” by Canadian doctor Lieutenant-Colonel John McCrae . In the latter poem, McCrae writes from the perspective of the fallen soldiers:

Published in 1915, the poem inspired the use of the poppy as a symbol of remembrance.

Visual artists like Otto Dix of Germany and British painters Wyndham Lewis, Paul Nash and David Bomberg used their firsthand experience as soldiers in World War I to create their art, capturing the anguish of trench warfare and exploring the themes of technology, violence and landscapes decimated by war.

The Eastern Front

On the Eastern Front of World War I, Russian forces invaded the German-held regions of East Prussia and Poland but were stopped short by German and Austrian forces at the Battle of Tannenberg in late August 1914.

Despite that victory, Russia’s assault forced Germany to move two corps from the Western Front to the Eastern, contributing to the German loss in the Battle of the Marne.

Combined with the fierce Allied resistance in France, the ability of Russia’s huge war machine to mobilize relatively quickly in the east ensured a longer, more grueling conflict instead of the quick victory Germany had hoped to win under the Schlieffen Plan .

Russian Revolution

From 1914 to 1916, Russia’s army mounted several offensives on World War I’s Eastern Front but was unable to break through German lines.

Defeat on the battlefield, combined with economic instability and the scarcity of food and other essentials, led to mounting discontent among the bulk of Russia’s population, especially the poverty-stricken workers and peasants. This increased hostility was directed toward the imperial regime of Czar Nicholas II and his unpopular German-born wife, Alexandra.

Russia’s simmering instability exploded in the Russian Revolution of 1917, spearheaded by Vladimir Lenin and the Bolsheviks , which ended czarist rule and brought a halt to Russian participation in World War I.

Russia reached an armistice with the Central Powers in early December 1917, freeing German troops to face the remaining Allies on the Western Front.

America Enters World War I

At the outbreak of fighting in 1914, the United States remained on the sidelines of World War I, adopting the policy of neutrality favored by President Woodrow Wilson while continuing to engage in commerce and shipping with European countries on both sides of the conflict.

Neutrality, however, it was increasingly difficult to maintain in the face of Germany’s unchecked submarine aggression against neutral ships, including those carrying passengers. In 1915, Germany declared the waters surrounding the British Isles to be a war zone, and German U-boats sunk several commercial and passenger vessels, including some U.S. ships.

Widespread protest over the sinking by U-boat of the British ocean liner Lusitania —traveling from New York to Liverpool, England with hundreds of American passengers onboard—in May 1915 helped turn the tide of American public opinion against Germany. In February 1917, Congress passed a $250 million arms appropriations bill intended to make the United States ready for war.

Germany sunk four more U.S. merchant ships the following month, and on April 2 Woodrow Wilson appeared before Congress and called for a declaration of war against Germany.

Gallipoli Campaign

With World War I having effectively settled into a stalemate in Europe, the Allies attempted to score a victory against the Ottoman Empire, which entered the conflict on the side of the Central Powers in late 1914.

After a failed attack on the Dardanelles (the strait linking the Sea of Marmara with the Aegean Sea), Allied forces led by Britain launched a large-scale land invasion of the Gallipoli Peninsula in April 1915. The invasion also proved a dismal failure, and in January 1916 Allied forces staged a full retreat from the shores of the peninsula after suffering 250,000 casualties.

Did you know? The young Winston Churchill, then first lord of the British Admiralty, resigned his command after the failed Gallipoli campaign in 1916, accepting a commission with an infantry battalion in France.

British-led forces also combated the Ottoman Turks in Egypt and Mesopotamia , while in northern Italy, Austrian and Italian troops faced off in a series of 12 battles along the Isonzo River, located at the border between the two nations.

Battle of the Isonzo

The First Battle of the Isonzo took place in the late spring of 1915, soon after Italy’s entrance into the war on the Allied side. In the Twelfth Battle of the Isonzo, also known as the Battle of Caporetto (October 1917), German reinforcements helped Austria-Hungary win a decisive victory.

After Caporetto, Italy’s allies jumped in to offer increased assistance. British and French—and later, American—troops arrived in the region, and the Allies began to take back the Italian Front.

World War I at Sea

In the years before World War I, the superiority of Britain’s Royal Navy was unchallenged by any other nation’s fleet, but the Imperial German Navy had made substantial strides in closing the gap between the two naval powers. Germany’s strength on the high seas was also aided by its lethal fleet of U-boat submarines.

After the Battle of Dogger Bank in January 1915, in which the British mounted a surprise attack on German ships in the North Sea, the German navy chose not to confront Britain’s mighty Royal Navy in a major battle for more than a year, preferring to rest the bulk of its naval strategy on its U-boats.

The biggest naval engagement of World War I, the Battle of Jutland (May 1916) left British naval superiority on the North Sea intact, and Germany would make no further attempts to break an Allied naval blockade for the remainder of the war.

World War I Planes

World War I was the first major conflict to harness the power of planes. Though not as impactful as the British Royal Navy or Germany’s U-boats, the use of planes in World War I presaged their later, pivotal role in military conflicts around the globe.

At the dawn of World War I, aviation was a relatively new field; the Wright brothers took their first sustained flight just eleven years before, in 1903. Aircraft were initially used primarily for reconnaissance missions. During the First Battle of the Marne, information passed from pilots allowed the allies to exploit weak spots in the German lines, helping the Allies to push Germany out of France.

The first machine guns were successfully mounted on planes in June of 1912 in the United States, but were imperfect; if timed incorrectly, a bullet could easily destroy the propeller of the plane it came from. The Morane-Saulnier L, a French plane, provided a solution: The propeller was armored with deflector wedges that prevented bullets from hitting it. The Morane-Saulnier Type L was used by the French, the British Royal Flying Corps (part of the Army), the British Royal Navy Air Service and the Imperial Russian Air Service. The British Bristol Type 22 was another popular model used for both reconnaissance work and as a fighter plane.

Dutch inventor Anthony Fokker improved upon the French deflector system in 1915. His “interrupter” synchronized the firing of the guns with the plane’s propeller to avoid collisions. Though his most popular plane during WWI was the single-seat Fokker Eindecker, Fokker created over 40 kinds of airplanes for the Germans.

The Allies debuted the Handley-Page HP O/400, the first two-engine bomber, in 1915. As aerial technology progressed, long-range heavy bombers like Germany’s Gotha G.V. (first introduced in 1917) were used to strike cities like London. Their speed and maneuverability proved to be far deadlier than Germany’s earlier Zeppelin raids.

By the war’s end, the Allies were producing five times more aircraft than the Germans. On April 1, 1918, the British created the Royal Air Force, or RAF, the first air force to be a separate military branch independent from the navy or army. 

Second Battle of the Marne

With Germany able to build up its strength on the Western Front after the armistice with Russia, Allied troops struggled to hold off another German offensive until promised reinforcements from the United States were able to arrive.

On July 15, 1918, German troops launched what would become the last German offensive of the war, attacking French forces (joined by 85,000 American troops as well as some of the British Expeditionary Force) in the Second Battle of the Marne . The Allies successfully pushed back the German offensive and launched their own counteroffensive just three days later.

After suffering massive casualties, Germany was forced to call off a planned offensive further north, in the Flanders region stretching between France and Belgium, which was envisioned as Germany’s best hope of victory.

The Second Battle of the Marne turned the tide of war decisively towards the Allies, who were able to regain much of France and Belgium in the months that followed.

The Harlem Hellfighters and Other All-Black Regiments

By the time World War I began, there were four all-Black regiments in the U.S. military: the 24th and 25th Infantry and the 9th and 10th Cavalry. All four regiments comprised of celebrated soldiers who fought in the Spanish-American War and American-Indian Wars , and served in the American territories. But they were not deployed for overseas combat in World War I. 

Blacks serving alongside white soldiers on the front lines in Europe was inconceivable to the U.S. military. Instead, the first African American troops sent overseas served in segregated labor battalions, restricted to menial roles in the Army and Navy, and shutout of the Marines, entirely. Their duties mostly included unloading ships, transporting materials from train depots, bases and ports, digging trenches, cooking and maintenance, removing barbed wire and inoperable equipment, and burying soldiers.

Facing criticism from the Black community and civil rights organizations for its quotas and treatment of African American soldiers in the war effort, the military formed two Black combat units in 1917, the 92nd and 93rd Divisions . Trained separately and inadequately in the United States, the divisions fared differently in the war. The 92nd faced criticism for their performance in the Meuse-Argonne campaign in September 1918. The 93rd Division, however, had more success. 

With dwindling armies, France asked America for reinforcements, and General John Pershing , commander of the American Expeditionary Forces, sent regiments in the 93 Division to over, since France had experience fighting alongside Black soldiers from their Senegalese French Colonial army. The 93 Division’s 369 regiment, nicknamed the Harlem Hellfighters , fought so gallantly, with a total of 191 days on the front lines, longer than any AEF regiment, that France awarded them the Croix de Guerre for their heroism. More than 350,000 African American soldiers would serve in World War I in various capacities.

Toward Armistice

By the fall of 1918, the Central Powers were unraveling on all fronts.

Despite the Turkish victory at Gallipoli, later defeats by invading forces and an Arab revolt that destroyed the Ottoman economy and devastated its land, and the Turks signed a treaty with the Allies in late October 1918.

Austria-Hungary, dissolving from within due to growing nationalist movements among its diverse population, reached an armistice on November 4. Facing dwindling resources on the battlefield, discontent on the homefront and the surrender of its allies, Germany was finally forced to seek an armistice on November 11, 1918, ending World War I.

Treaty of Versailles

At the Paris Peace Conference in 1919, Allied leaders stated their desire to build a post-war world that would safeguard itself against future conflicts of such a devastating scale.

Some hopeful participants had even begun calling World War I “the War to End All Wars.” But the Treaty of Versailles , signed on June 28, 1919, would not achieve that lofty goal.

Saddled with war guilt, heavy reparations and denied entrance into the League of Nations , Germany felt tricked into signing the treaty, having believed any peace would be a “peace without victory,” as put forward by President Wilson in his famous Fourteen Points speech of January 1918.

As the years passed, hatred of the Versailles treaty and its authors settled into a smoldering resentment in Germany that would, two decades later, be counted among the causes of World War II .

World War I Casualties

World War I took the lives of more than 9 million soldiers; 21 million more were wounded. Civilian casualties numbered close to 10 million. The two nations most affected were Germany and France, each of which sent some 80 percent of their male populations between the ages of 15 and 49 into battle.

The political disruption surrounding World War I also contributed to the fall of four venerable imperial dynasties: Germany, Austria-Hungary, Russia and Turkey.

Legacy of World War I

World War I brought about massive social upheaval, as millions of women entered the workforce to replace men who went to war and those who never came back. The first global war also helped to spread one of the world’s deadliest global pandemics, the Spanish flu epidemic of 1918, which killed an estimated 20 to 50 million people.

World War I has also been referred to as “the first modern war.” Many of the technologies now associated with military conflict—machine guns, tanks , aerial combat and radio communications—were introduced on a massive scale during World War I.

The severe effects that chemical weapons such as mustard gas and phosgene had on soldiers and civilians during World War I galvanized public and military attitudes against their continued use. The Geneva Convention agreements, signed in 1925, restricted the use of chemical and biological agents in warfare and remain in effect today.

Historical Context: The Global Effect of World War I

By steven mintz.

A recent list of the hundred most important news stories of the twentieth century ranked the onset of World War I eighth. This is a great error. Just about everything that happened in the remainder of the century was in one way or another a result of World War I, including the Bolshevik Revolution in Russia, World War II, the Holocaust, and the development of the atomic bomb. The Great Depression, the Cold War, and the collapse of European colonialism can also be traced, at least indirectly, to the First World War.

World War I killed more people--more than 9 million soldiers, sailors, and flyers and another 5 million civilians--involved more countries--28--and cost more money--$186 billion in direct costs and another $151 billion in indirect costs--than any previous war in history. It was the first war to use airplanes, tanks, long range artillery, submarines, and poison gas. It left at least 7 million men permanently disabled.

World War I probably had more far-reaching consequences than any other proceeding war. Politically, it resulted in the downfall of four monarchies--in Russia in 1917, in Austria-Hungary and Germany in 1918, and in Turkey in 1922. It contributed to the Bolshevik rise to power in Russia in 1917 and the triumph of fascism in Italy in 1922. It ignited colonial revolts in the Middle East and in Southeast Asia.

Economically, the war severely disrupted the European economies and allowed the United States to become the world's leading creditor and industrial power. The war also brought vast social consequences, including the mass murder of Armenians in Turkey and an influenza epidemic that killed over 25 million people worldwide.

Few events better reveal the utter unpredictability of the future. At the dawn of the 20th century, most Europeans looked forward to a future of peace and prosperity. Europe had not fought a major war for 100 years. But a belief in human progress was shattered by World War I, a war few wanted or expected. At any point during the five weeks leading up to the outbreak of fighting the conflict might have been averted. World War I was a product of miscalculation, misunderstanding, and miscommunication.

No one expected a war of the magnitude or duration of World War I. At first the armies relied on outdated methods of communication, such as carrier pigeons. The great powers mobilized more than a million horses. But by the time the conflict was over, tanks, submarines, airplane-dropped bombs, machine guns, and poison gas had transformed the nature of modern warfare. In 1918, the Germans fired shells containing both tear gas and lethal chlorine. The tear gas forced the British to remove their gas masks; the chlorine then scarred their faces and killed them.

In a single day at the Battle of the Somme in 1916, 100,000 British troops plodded across no man's land into steady machine-gun fire from German trenches a few yards away. Some 60,000 were killed or wounded. At the end of the battle, 419,654 British men were killed, missing, or wounded.Four years of war killed a million troops from the British Empire, 1.5 million troops from the Hapsburg Empire, 1.7 million French troops, 1.7 million Russians, and 2 million German troops. The war left a legacy of bitterness that contributed to World War II twenty-one years later.

How did wwi reshape the modern world.

A hundred years after the end of the “war to end all wars,” USC experts discuss its surprising impact and how it affects us even today

One hundred years ago Sunday, the Allies and Germany agreed to an armistice ending World War I. The Great War claimed 40 million lives — but also serves as an unexpected pivot point for modern civilization.

“World War I is an amazingly important and underappreciated moment in history,” said Nicholas J. Cull , historian in the USC Annenberg School for Communication and Journalism.

“The war ended when people were able to articulate a vision of the future, an optimism about how things were going to be better with nations working together.”

The war also rewrote the world map. Russia quit the war as domestic unrest triggered the Bolshevik revolution, rise of Communism and the Cold War. The Middle East changed with the defeat of Turkey and Britain’s pledge for a Jewish state in Palestine. The Western powers, fatigued by war, yielded to isolationism and appeasement as the Third Reich emerged, triggering World War II and the Holocaust.

Impact of World War I on medical care

Another thing forever changed by the war: medicine.

“Prior to WWI, most of the medicine practiced around the world was fairly archaic,” said Carl Chudnofsky , chair and professor of clinical emergency medicine at the Keck School of Medicine of USC.

The best physicians and researchers were in the military … so that led to great discoveries that made a huge difference for public health. Carl Chudnofsky

“But WWI was a time when the best physicians and researchers were in the military, not in civilian life, caring for patients, so that led to great discoveries that made a huge difference for public health.”

Chudnofsky points out that disease awareness and prevention leaped forward during WWI, first to heal soldiers and later for civilians. Medical advances included screening for tuberculosis, treatment for tetanus, vaccines for typhoid, prevention of venereal disease and disinfection for surgery.

Triage for medical attention emerged from the trenches of WWI to become a fixture in battlefields and other disasters. And mobile field hospitals and medical trains were innovations that helped evacuate casualties and save thousands of lives — techniques now common on battlefields.

Impact of World War I, the ‘war to end all wars’

And although World War I was called the “war to end all wars,” the U.S. has been at war somewhere around the world almost ever since. Michael Messner , professor of sociology at theUSC Dornsife College of Letters, Arts and Sciences, said that’s because war and militarism are ingrained in American DNA.

“It’s part of our national identity, the old ideas of expansionism, white man’s burden and Manifest Destiny in the previous century,” he said. “We idealize war and military.”

First World War (1914-1918): Causes and Consequences

Last updated on October 10, 2023 by Alex Andrews George

Table of Contents

The Two Groups: Allies vs Central Powers

Causes of the First World War

In the background there were many conflicts between European nations. Nations grouped among themselves to form military alliances as there were tension and suspicion among them. The causes of the First World War were:

(1) Conflict between Imperialist countries: Ambition of Germany

• Conflict between old imperialist countries (Eg: Britain and France) vs new imperialist countries (Eg: Germany).
• Germany ship – Imperator.
• German railway line – from Berlin to Baghdad.

(2) Ultra Nationalism

• Pan Slav movement – Russian, Polish, Czhech, Serb, Bulgaria and Greek.
• Pan German movement.

(3) Military Alliance

• Triple Alliance or Central Powers (1882) – Germany, Italy, Austria-Hungary.
• Triple Entente or Allies (1907) – Britain, France, Russia.

Note: Although Italy was a member of the Triple Alliance alongside Germany and Austria-Hungary, it did not join the Central Powers, as Austria-Hungary had taken the offensive, against the terms of the alliance.   These alliances were reorganised and expanded as more nations entered the war: Italy, Japan and the United States joined the Allies, while the Ottoman Empire and Bulgaria joined the Central Powers.

(4) International Anarchy

• Secret agreement between Britain and France allowing Britain to control Egypt and France to take over Morocco. Germany opposed, but settled with a part of French Congo.
• Hague conference of 1882 and 1907 failed to emerge as an international organisation.

(5) Balkan Wars

• Many Balkan nations (Serbia, Bulgaria, Albania, Greece and Montenegro) were under the control of Turkey. They defeated Turkey in the First Balkan War. The subsequent war was between the Balkan countries themselves – Eg:  Serbia vs Bulgaria.
• Defeated countries like Turkey and Bulgaria sought German help.

(6) Alsace-Loraine

• During German unification, Germany got Alsace-Loraine from France. France wanted to capture Alsace-Loraine back from Germany.

(7) Immediate Cause: assassination of Francis Ferdinand

• Austrian Archduke Francis Ferdinand was assassinated by a Serbian native (in Bosnia). Austria declared war on Serbia on 28th July, 1914. [Reason for assassination: Annexation by Austria the Bosnia-Herzegovina, against the congress of Berlin, 1878]

The Course of the War

• Group 1 (Allies): Serbia, Russia, Britian, France, USA, Belgium, Portugal, Romania etc
• Group 2 (Central Powers): Austria-Hungary, Germany, Italy, Turkey, Bulgaria etc.
• War on Western Side: Battle of Marne.
• War on Eastern Side: Battle of Tennenberg (Russia was defeated).
• War on the Sea: Batter of Dogger Bank (Germany was defeated), Battle of Jutland (Germany retreated).
• USA entered in 1917.
• Russia withdrew in 1917 after October Revolution.

Treaty of Versailles, Paris

• Germany signed a treaty with Allies (Triple Entente) on 28th June 1919. It was signed at Versailles, near Paris. (14 points)
• Leaders: Clemenceau – France, Lloyd George – Britain, Woodrow Wilson – USA, Orlando – Italy.

Treaties after World War I

• Treaty of Paris – with Germany.
• Treaty of St.Germaine – with Austria.
• Treaty of Trianon- with Hungary.
• Treaty of Neuilly – with Bulgaria.
• Treaty of Severes – with Turkey.

Consequences of First World War

• Rule of King ended in Germany: Germany became a republic on November 1918. The German Emperor Kaiser William II fled to Holland.
• Around 1 crore people were killed.
• Unemployment and famine.
• The fall of Russian empire after October revolution (1917) which resulted in the formation of USSR (1922)
• Emergence of USA as a super power.
• Beginning of the end of European supremacy.
• Japan became a powerful country in Asia.
• Poland, Yugoslavia and Czechoslovakia became new independent states.
• Baltic countries – Estonia, Latvia and Lithvania – became independent.
• Rule of Ottamans came to an end in Turkey.
• New boundary lines were drawn for Austria, Germany and Turkey.
• Strengthened independence movements in Asia and Africa.
• League of Nations came into being.
• Germany had to return Alsace-Loraine to France.
• German colonies were shared.
• Germany gave up Saar coal field.
• Germany gave up Polish corridor, and made city of Danzig independent.
• Monarchy was abolished in Germany, Austria, Hungary, Turkey and Russia.
• The harsh clauses of the Treaty of Versailles finally resulted in the second world war .

World War I, also known as the First World War, was a massive conflict that occurred from July 28, 1914, to November 11, 1918. It involved major global powers divided into two alliances: the Allies (comprising the British Empire, France, and the Russian Empire) and the Central Powers (Germany and Austria-Hungary). The war’s causes were multifaceted, including conflicts between imperialist countries, Germany’s ambitions, ultra-nationalism, military alliances, international anarchy, Balkan Wars, Alsace-Lorraine dispute, and the assassination of Francis Ferdinand. The war led to significant consequences and the Treaty of Versailles in Paris, which aimed to establish peace. 🌍💥🤔

World War I, a colossal conflict from 1914 to 1918, involved major powers forming two opposing alliances: the Allies (including the British Empire, France, and Russia) against the Central Powers (Germany and Austria-Hungary). Key causes were imperialist rivalries, with Germany’s ambitions and military buildup, ultra-nationalism fueling movements like Pan-Slav and Pan-German, military alliances (Triple Alliance and Triple Entente), and international disputes like Egypt and Morocco. These tensions escalated until the assassination of Francis Ferdinand triggered the war. The aftermath brought the Treaty of Versailles and reshaped the world order, marking a pivotal moment in history. 🌍🔥🕊️ #WWI #History

5 Key Causes of World War I

Illustration by Hugo Lin. ThoughtCo.

• M.A., History, University of Florida
• B.A., History, University of Florida

World War I, known as the "war to end all wars," occurred between July 1914 and November 11, 1918. By the end of the war, over 17 million people had been killed, including over 100,000 American troops. While the causes of the war are infinitely more complicated than a simple timeline of events, and are still debated and discussed to this day, the list below provides an overview of the most frequently-cited events that led to war. 

Watch Now: 5 Causes of World War I

Mutual defense alliances.

Countries throughout the world have always made mutual defense agreements with their neighbors, treaties that could pull them into battle. These treaties meant that if one country was attacked, the allied countries were bound to defend them. Before World War 1 began, the following alliances existed:

• Russia and Serbia
• Germany and Austria-Hungary
• France and Russia
• Britain and France and Belgium
• Japan and Britain

When Austria-Hungary declared war on Serbia, Russia got involved to defend Serbia. Germany, seeing that Russia was mobilizing, declared war on Russia. France was then drawn in against Germany and Austria-Hungary. Germany attacked France by marching through Belgium pulling Britain into war. Then Japan entered the war to support its British allies. Later, Italy and the United States would enter on the side of the Allies (Britain, France, Russia, etc.).

Imperialism

Imperialism is when a country increases their power and wealth by bringing additional territories under their control, usually without outright colonizing or resettling them. Before World War I, several European countries had made competing imperialistic claims in Africa and parts of Asia, making them points of contention. Because of the raw materials these areas could provide, tensions around which country had the right to exploit these areas ran high. The increasing competition and desire for greater empires led to an increase in confrontation that helped push the world into World War I.

As the world entered the 20th century, an arms race had begun, primarily over the number of each country's warships, and the increasing size of their armies—countries began training more and more of their young men to be prepared for battle. The warships themselves increased in size, number of guns, speed, method of propulsion, and quality armor, beginning in 1906 with Britain's HMS Dreadnought . Dreadnought   was soon out-classed as the Royal Navy and Kaiserliche Marine quickly expanded their ranks with increasingly modern and powerful warships. 

By 1914, Germany had nearly 100 warships and two million trained soldiers. Great Britain and Germany both greatly increased their navies in this time period. Further, in Germany and Russia particularly, the military establishment began to have a greater influence on public policy. This increase in militarism helped push the countries involved into war.

Nationalism

Much of the origin of the war was based on the desire of the Slavic peoples in Bosnia and Herzegovina to no longer be part of Austria-Hungary but instead be part of Serbia. This specific essentially nationalistic and ethnic revolt led directly to the assassination of Archduke Ferdinand , which was the event that tipped the scales to war.

But more generally, nationalism in many of the countries throughout Europe contributed not only to the beginning but to the extension of the war across Europe and into Asia. As each country tried to prove their dominance and power, the war became more complicated and prolonged.

Immediate Cause: Assassination of Archduke Franz Ferdinand

The immediate cause of World War I that made the aforementioned items come into play (alliances, imperialism, militarism, and nationalism) was the assassination of Archduke Franz Ferdinand  of Austria-Hungary. In June 1914, a Serbian-nationalist terrorist group called the Black Hand sent groups to assassinate the Archduke. Their first attempt failed when a driver avoided a grenade thrown at their car. However, later that day a Serbian nationalist named Gavrilo Princip shot the Archduke and his wife while they were driving through Sarajevo, Bosnia which was part of Austria-Hungary. They died of their wounds.

The assassination was in protest to Austria-Hungary having control of this region: Serbia wanted to take over Bosnia and Herzegovina. The assassination of Ferdinand led to Austria-Hungary declaring war on Serbia. When Russia began to mobilize to defend its alliance with Serbia, Germany declared war on Russia. Thus began the expansion of the war to include all those involved in the mutual defense alliances.

The War to End All Wars

World War I saw a change in warfare, from the hand-to-hand style of older wars to the inclusion of weapons that used technology and removed the individual from close combat. The war had extremely high casualties over 15 million dead and 20 million injured. The face of warfare would never be the same again.

World War 1 Origins (How and Why the War Started) Essay

Introduction, causes of world war 1.

Bibliography

Since time immemorial the world has witnessed wars between different groups, states, countries, and allies. Initially, the motive behind wars was survival. Ancient people fought in order to usurp land for cultivation. Gradually, as the world population grew, the motives behind wars became multifarious.

Different groups and countries started fighting with each other in order to gain control of areas where there were natural resources such as gold. Another reason for war was to gain access to routes generally used for movement of commodities from the starting place to the consumption areas.

It is understood that after a war, one group prospered at the cost of another. Religion also has been an instigating factor for many wars. However, in all the wars, the motive was to gain advantage of some sort.

During the past years, when countries came together as allies, there have been instances when allies of a particular group had to go to war just because they wanted to safeguard themselves from the disadvantages of not participating in the war. In this paper, we shall discuss the reasons that led to World War 1. “World War 1 began in eastern Europe. The war started when Serbia, Austria-Hungary, Russia, and Germany decided that war or the risk of war was an acceptable policy option [1] ”.

General Causes

1879 onwards, the world witnessed formation of alliances between nations having similar interests. Following are some of the major alliances that took place:

• The Dual Alliance: Germany and Austria-Hungary entered into an alliance in 1879 in order to defend against Russia.
• Austro-Serbian Alliance: Austria-Hungary and Serbia entered into an alliance in 1881 in order to prevent Russia from asserting power in Serbia.
• The Triple Alliance: Germany and Austria-Hungary entered into an alliance with Italy in 1882 so that the latter could not favor Russia’s moves.
• Franco-Russian Alliance: Russia and France entered into an alliance in 1894 in order to protect their countries from the Dual Alliance of Germany and Austria-Hungary.
• Entente Cordiale: France and Britain entered into a formal agreement in 1904 in order to protect each other’s interests.
• Anglo-Russian Entente: Britain and Russia entered into a formal agreement in 1907 in order to protect each other’s interests.
• Triple Entente: Russia, France and Britain entered into an alliance to counteract Germany’s growing threats. Later, in 1914 and under the same alliance, all the three countries concurred that they will not sign any peace treaty without mutual consent.

All these alliances (from 1879 to 1914) forced some countries to go to war just because they were in some alliance.

Imperialism

Imperialism is a term used for instances where any country usurps any other country’s land and asserts its supremacy and power. Due to the incessant progress of industrialization, countries felt the need of venturing into fresh marketplaces.

By the year 1900, Britain had extended its empire in five continents and France controlled major parts of Africa. The increase of both these countries’ power did not go well with Germany; Germany had only small areas under its rule. Following is a map that depicts the colonies of these three major European players in 1914.

Source: Web.

William Anthony Hay claims that according to McMeekin, a tutor of international relations, “The war’s real catalyst lay in Russia’s ambition to supplant the waning Ottoman Empire in the Near East and to control the Turkish straits – the Bosphorus and Dardanelles – linking the Black Sea and the Mediterranean [2] ”.

But Richard Evans contradicts this opinion by stating that “In the end it was the Austro-Hungarian invasion of Serbia that set off the process that ended in the outbreak of World War 1, not Russian ambitions in the Straits [3] . But if we think logically, no country will enter into a war without personal interests.

Alliances were also made to serve individual interests. So it is wrong to say that Russia did not have any interest or ambitions in the Straits. Russia was an industrialized nation and needed to sell its products to people in other nations. For this purpose, it needed a safe passage and new markets.

When any country gives preference to its army, it is said to be following militarism. The growing alliances among various nations prompted nations to empower their army with more arms and ammunitions. France and Germany doubled the strengths of their respective armies.

Britain and Germany seemed to be in a competition of better sea control. In 1906, Britain launched the ‘Dreadnought’, considered to be a very efficient battleship. Following the footsteps, Germany also launched its own version of impressive battleships. The following illustration shows how Germany planned to attack France in case Russia attacked Germany; France and Russia were allies. So due to the alliance, Russia was bound to retaliate when one of its allies was attacked.

“A military revolution occurred in the seventeenth century. The most important of the many changes was a considerable growth in the size of the armies. Those large forces could no longer live off the land: steal supplies from the populace [4] ”.

Nationalism

We all have love for our respective countries. So did the people of that period. Austria-Hungary and Serbia had different radical groups trying to free their states from foreign involvement. Both Italy and Germany were divided. People of these countries wanted unification. “Along with the history of imperial machinations, however, World War 1 should be understood in the context of the popular imagination and the growth of nationalist sentiment in Europe [5] ”.

Moroccan Crisis

As part of an understanding, Britain gave control of Morocco to France in 1904. The Moroccan people wanted freedom. Germany, in order to take an advantage of the situation, proclaimed its support for the freedom of Morocco. A conference was held that allowed France to continue its control over Morocco and a war was averted. Again, in 1911, Germany started pronouncing its support for the Moroccan independence but again it was persuaded to compromise its stand on the issue.

Bosnian Crisis

Bosnia (a Turkish province) was taken over by Austria-Hungary in 1908. This action of Austria-Hungary did not go well with the Serbians. The Serbians thought Bosnia was under them. As such, a conflict aroused. Serbia proclaimed war over Austria-Hungary. Russia supported Serbia and Germany supported Austria-Hungary. A war was about to start but at the nick of the time Russia backed off and the war was averted.

But tensions were still mounting up between Serbia and Austria-Hungary. “It is true that during July the German decision makers sometimes expressed the hope that the conflict would be localized: in other words that Austria would be able to vanquish Serbia without Russian Intervention [6] ”. Dale Copeland argues that “Germany actively sought war in July 1914 and that German leaders by the end of July preferred world war to a negotiated peace, even to one that gave Austria most of what it wanted [7] ”.

The Immediate Trigger

World War 1 started in the year 1914. The assassination of Austria’s Archduke, Franz Ferdinand, acted as a trigger to World War 1. Franz Ferdinand and his wife were murdered in 1914 by Gavrilo Princip, member of a Bosnian radical group. “The crumbling Austro-Hungarian Empire decided, after the assassination on 28 June, to take action against Serbia, which was suspected of being behind the murder [8] ”.

This was considered to be an immediate reason for the war but the real reasons seem to be more complex and are still topics of debate among various historians. According to William Anthony Hay, “Germany bears responsibility for the war, in this view, because its leaders deliberately turned a regional clash between Austria-Hungary and Serbia into an existential Struggle of rival alliances [9] ”.

Hay is right in his opinion because history reveals that there were other options with Germany that could have averted the war. But since Germany wanted to gain on its own interests, it forced other countries to plunge into a war that they did not intend. “The size and wealth of the conquered Eastern territories easily outweighed what would have been lost had the Germans withdrawn from Belgium and France. Had they done so, France might have made peace and the anti-German coalition collapsed [10] ”.

All these instances make us to believe that Germany was behind waging the World War 1. In its ambitions to usurp power, Germany was thought to have instigated the war. But it is to be understood that down the years, historians put an end to the controversy as to which country was responsible for the World War 1.

Historians from the two main countries (Germany and France) came to an understanding that none of their countries should be blamed for instigating World War 1. It was the policies of militarization of each of the participating countries that led to the war.

But certain facts still point the finger towards Germany. After the war started, some confidential documents were discovered that suggested that the German government had vast plans of extending its territory due to the economic requirements.

The 4 M-A-I-N Causes of World War One

Alex Browne

28 sep 2021.

It’s possibly the single most pondered question in history – what caused World War One? It wasn’t, like in World War Two, a case of a single belligerent pushing others to take a military stand. It didn’t have the moral vindication of resisting a tyrant.

Rather, a delicate but toxic balance of structural forces created a dry tinder that was lit by the assassination of Archduke Franz Ferdinand in Sarajevo . That event precipitated the July Crisis, which saw the major European powers hurtle toward open conflict.

The M-A-I-N acronym – militarism, alliances, imperialism and nationalism – is often used to analyse the war, and each of these reasons are cited to be the 4 main causes of World War One. It’s simplistic but provides a useful framework.

The late nineteenth century was an era of military competition, particularly between the major European powers. The policy of building a stronger military was judged relative to neighbours, creating a culture of paranoia that heightened the search for alliances. It was fed by the cultural belief that war is good for nations.

Germany in particular looked to expand its navy. However, the ‘naval race’ was never a real contest – the British always s maintained naval superiority.  But the British obsession with naval dominance was strong. Government rhetoric exaggerated military expansionism.  A simple naivety in the potential scale and bloodshed of a European war prevented several governments from checking their aggression.

A web of alliances developed in Europe between 1870 and 1914 , effectively creating two camps bound by commitments to maintain sovereignty or intervene militarily – the Triple Entente and the Triple Alliance.

• The Triple Alliance of 1882 linked Germany, Austria-Hungary and Italy.
• The Triple Entente of 1907 linked France, Britain and Russia.

A historic point of conflict between Austria Hungary and Russia was over their incompatible Balkan interests, and France had a deep suspicion of Germany rooted in their defeat in the 1870 war.

The alliance system primarily came about because after 1870 Germany, under Bismarck, set a precedent by playing its neighbours’ imperial endeavours off one another, in order to maintain a balance of power within Europe

Imperialism

Imperial competition also pushed the countries towards adopting alliances. Colonies were units of exchange that could be bargained without significantly affecting the metro-pole. They also brought nations who would otherwise not interact into conflict and agreement. For example, the Russo-Japanese War (1905) over aspirations in China, helped bring the Triple Entente into being.

It has been suggested that Germany was motivated by imperial ambitions to invade Belgium and France. Certainly the expansion of the British and French empires, fired by the rise of industrialism and the pursuit of new markets, caused some resentment in Germany, and the pursuit of a short, aborted imperial policy in the late nineteenth century.

However the suggestion that Germany wanted to create a European empire in 1914 is not supported by the pre-war rhetoric and strategy.

Nationalism

Nationalism was also a new and powerful source of tension in Europe. It was tied to militarism, and clashed with the interests of the imperial powers in Europe. Nationalism created new areas of interest over which nations could compete.

For example, The Habsburg empire was tottering agglomeration of 11 different nationalities, with large slavic populations in Galicia and the Balkans whose nationalist aspirations ran counter to imperial cohesion. Nationalism in the Balkan’s also piqued Russia’s historic interest in the region.

Indeed, Serbian nationalism created the trigger cause of the conflict – the assassination of the heir to the Austro-Hungarian throne, Archduke Franz Ferdinand.

The spark: the assassination

Ferdinand and his wife were murdered in Sarajevo by Gavrilo Princip, a member of the Bosnian Serbian nationalist terrorist organization the ‘Black Hand Gang.’ Ferdinand’s death, which was interpreted as a product of official Serbian policy, created the July Crisis – a month of diplomatic and governmental miscalculations that saw a domino effect of war declarations initiated.

The historical dialogue on this issue is vast and distorted by substantial biases. Vague and undefined schemes of reckless expansion were imputed to the German leadership in the immediate aftermath of the war with the ‘war-guilt’ clause. The notion that Germany was bursting with newfound strength, proud of her abilities and eager to showcase them, was overplayed.

The first page of the edition of the ‘Domenica del Corriere’, an Italian paper, with a drawing by Achille Beltrame depicting Gavrilo Princip killing Archduke Franz Ferdinand of Austria in Sarajevo

The almost laughable rationalization of British imperial power as ‘necessary’ or ‘civilizing’ didn’t translate to German imperialism, which was ‘aggressive’ and ‘expansionist.’ There is an on-going historical discussion on who if anyone was most culpable.

Blame has been directed at every single combatant at one point or another, and some have said that all the major governments considered a golden opportunity for increasing popularity at home.

The Schlieffen plan could be blamed for bringing Britain into the war, the scale of the war could be blamed on Russia as the first big country to mobilise, inherent rivalries between imperialism and capitalism could be blamed for polarising the combatants. AJP Taylor’s ‘timetable theory’ emphasises the delicate, highly complex plans involved in mobilization which prompted ostensibly aggressive military preparations.

Every point has some merit, but in the end what proved most devastating was the combination of an alliance network with the widespread, misguided belief that war is good for nations, and that the best way to fight a modern war was to attack. That the war was inevitable is questionable, but certainly the notion of glorious war, of war as a good for nation-building, was strong pre-1914. By the end of the war, it was dead.

How it works

At the end of the 19th century and the beginning of the 20th century, the world was seething with an explosive, hair-trigger force waiting to explode. Capitalism was undergoing a transition to imperialism. The world’s territory was divided among the world’s most powerful nations. Colonies were scattered throughout Asia, Africa, and Latin America. The struggle between the new empires and the old ones was getting larger and larger.

As new forces began to snatch resources, uneven economic development and inadequate allocation of resources among countries created international pressure and conflict.

It was an era rife with nations enthusiastic about their military status’ and national pride. This perfect combination of pressure led to the beginning of the First World War in July 1914. There were four main causes of WWI — militarism, alliance, imperialism, and nationalism — that escalated into a global conflict. This free essay about the causes of WWI will explore the interconnectedness of these four concepts.

Militarism is when a country develops strong military and advanced technological weapons to pursue its own interests aggressively. This tactic highlights the national status and is a means to protect, expand, and intervene in territorial disputes as needed. During this time, nations raced to create advanced-power weapons and get them into the hands of their soldiers, a competition referred to as an arms race. Nations were investing in the idea that a strong military indicated a strong country, and those with the most progressive technology and efficient troops were perceived as the most powerful adversaries.) Before World War I, the most drastic forced competition was between Great Britain and Germany, respectively, showing their supremacy in military powers. This embrace of militarism, while not unique to these countries, also meant other nations were prepared for warfare.

In the early 20th Century, Great Britain possessed the strongest naval forces of developed nations. The battle-hardened British Navy helped Great Britain conquer a quarter of the world’s landmass. In 1889, the British Parliament passed the “Naval Defense Act,” which effectively doubled the size of the established British navy and established its size as even larger than the next two competing nation’s navy’s combined, with 62 warships of over 5,000 tons possessed by the British Navy, while the Germans had only 12.

Britain saw Germany as a potential military threat and continued to intensify its efforts to develop its military, especially the Navy. This was largely due to Germany’s leader, Kaiser Wilhelm II, who believed that formidable military strength would bring Germany untold prestige and power, firmly planting it as a center of European power. Germany passed the First Fleet Act in 1898, authorizing it to divert time and energy toward the development of a strong, competitive Navy.

Technological advancements followed suit, and Britain acquired new steel battleships, significant upgrades from previous wooden ones. The most imposing style was the steel ship the Dreadnought, equipped with 12-inch guns. Countries immediately aspired to create this new type of fearsome sea weapon. In 1914, Britain was the global leader in naval personnel, with 209,000 soldiers and 29 Dreadnought battleships. Meanwhile, Germany took second place with 79,000 soldiers and 17 Dreadnought ships but ultimately grew to have 38 of the fearsome ships.

Germany set Britain as a military target and then attempted to catch up with it. Germany Kaiser Wilhelm II believed that formidable military strength will bring Germany prestige and power. Meanwhile, Germany will be received respect from other European nations. If Germany could not possess powerful troops and advanced weapons, there would be no place and no discourse power for Germany in many European countries. Wilhelm II’s call boosted the passing of The German First Naval Law in 1898. The law claimed to begin the process of building a powerful navy.

After that, the second law required double the size of the German Navy from 19 battleships to 38. Wilhelm II’s encouragement supported the improvement of naval forces: “Germany is a young and growing empire. She has worldwide commerce, which is rapidly expanding and to which the legitimate ambition of Patriotic Germans refuses to assign any bounds. Germany must have a powerful fleet to protect that commerce and her manifold interests in even the most distant seas. She expects those interests to go on growing, and she must be able to champion them manfully in any quarter of the globe”. Moreover, Germany had the most powerful army, the Prussian army, which defended itself against the French in 1871, and the victory made them the most dangerous and effective military force in Europe. (Cleary)

The national governments of many European nations constantly instilled militarism into people’s minds, regarding leaders as heroes, advocating officers, and glorifying and romanticizing militarism. The nations permeated this idea into every corner. A strong military force could bring them prestige, protection, expansion, and improvement of the economy. Fighting, then, rather than negotiations, seemed to be the most reasonable method for resolving international conflict.

Militarism cannot begin a war alone. In order to succeed, nations need to form alliances. An alliance is an agreement of two or more countries in regard to political, military, or economic cooperation. European countries had many alliances before World War I, though they were often short-lived. Some were due to the emergence of new leaders or the replacement of old alliances with new ones. Some were due to the collapse of the countries or the betrayals between nations. Europe, the melting pot of ethnic and territorial disputes, is a place where change was possible and was happening fast.

One example of these fluid alliances was in 1873 with the Three Emperors’ League. Germany, Russia, and the Austro-Hungarian Empire. Within five years, Russia pulled out of the league to attend to its own national conflicts, and the league officially collapsed in 1878. Germany and Austria-Hungary formed The Dual Alliance in 1879, eventually adding Italy and becoming the Triple Alliance in 1882, allowing all three nations to support one another. In response, the Franco-Russian Alliance emerged, partnering with France and Russia in 1894.

Military alliances usually require signatory nations to support each other when they have wars with other countries, showing up in battle or with financial support, aligning against shared common enemies. Britain, Russia, and France overcame cultural differences and historical tensions to form a new alliance, the Triple Entente, in 1907. Britain was hoping to achieve victory in their arms race against Germany, while France was attempting to recapture provinces that had been previously ceded to Germany, uniting the two nations.

Additionally, Russia was still fighting with Austria-Hungary for control of the Balkan territory. These intertwined conflicts and disputes divided Europe into two major alliances, which lit the fuse of the bomb of World War I that followed. “The alliances created an excessively rigid diplomatic framework, within which relatively small detonators could produce huge explosions,” said A. J. P. Taylor, an English historian who specialized in 19th- and 20th-century European diplomacy. (European History)

The third contributing factor to World War I is Imperialism, loosely defined as using military might and force to overtake or influence other nations.s. Usually, colonies were controlled by the imperial nation or governed by a local puppet government. Military troops stationed locally in aid of maintaining order and suppressing rebellions. Colonization allowed imperial nations to acquire abundant resources, cheap laborers, and advantages of trade or commerce.

Before World War I, Great Britain was the largest and wealthiest dominant imperial power in the world. It possessed a quarter of the global landmass and was called “the empire on which the sun never sets” due to its immense size. Britain had colonies on every continent except Antarctica. The British Empire’s imperialism focused on expanding and maintaining trade. It used the colonies as factories to provide its home country with raw materials and manufactured goods as well as cheap labor. France maintained colonies in what are modern-day Vietnam, Laos, and Cambodia, some islands in the Pacific and Caribbean, small territories in South America, and areas of West Africa and India. German colonies included one province in China, Shandong)New Guinea, Samoa, numerous Pacific islands, and several areas in central and southwest Africa.

Before World War I, as empires grew stronger and larger, the competition between them also became fierce as they clamored for land, power, and money Germany and Italy were two relative newcomers to empire-building. When they first joined this imperial group, they found out much of the world’s land was controlled by their European neighbors. As such, Germany plotted to invade and take control of large swaths of East Africa. Within six years of their imperial outset, Germany controlled much of the region and established the German East Africa Company. However, the British and French Empires reckoned that Germany had threatened their holdings in Eastern Africa, increasing European tensions and conflicts.

The scramble for empire in Africa caused diplomatic incidents. One such conflict happened in Morocco in North-West Africa. Although Morocco was not a colony of France, its location of Morocco led it to be influenced by France’s control. France was trying to expand its rule in Morocco, but the German Kaiser stirred up tensions between France and Morocco by giving a speech that encouraged Moroccan independence. This had angered the French government and sparked wrathful diplomatic actions. When France attempted to suppress a revolt in Morocco, the German troops attacked an armed vessel at the Moroccan port of Agadir. Germany’s provocation almost touched off the war. Another event that made the European situation become unstable and intense. The decline of the Ottoman Empire attracted tensions of other European nations. After several failed wars, the Ottoman Empire almost collapsed. Other empires were eager to gain territory and influence in this dying empire. Austria-Hungary, Russia, Germany, France, and Britain all had colonial and trade interests in this region, leading to increased nationalism as they clamored to gain power.

Nationalism is when a country puts its own interests above all. It inspires citizens’ patriotism and a sense of national honor. Nationalism is the most significant contributor to World War I as it permeates militarism, alliances, and even imperialism. Nationalism is the base that triggers these three reasons. Countries pursued military strength and competed due to this nationalistic belief that they were superior to other neighboring nations. However, Nationalism is not relegated only to the matters of weapons.

Nationalism persuades people that their country is supreme in military, economic, and cultural aspects and is often displayed through music, visual arts, literature, and even theater. In a bid to convince people that their own countries are supreme, literature usually included libel or grand falsified statements to shed their opponents in a negative light.

Nationalism made countries excessively confident and gave them the illusion of military strength. Countries all believed their own military capacity was the best. The British were proud of the country’s naval power and developed economy. The French reckoned that they had solid defenses to block the attack of other nations. In Russia, the emperor believed he and his empire were under divine protection. They had the largest land force, which contained 1.5 million men, and their massive population made the country believe it would defeat other smaller countries easily. Germany’s advantages were shown in its developed advanced military weapons and increasing battleships and U-boats. The Germans believed their Schlieffen Plan would be effective and successful. (Nationalism)

Throughout Europe, great powers were considering an invasion of neighboring nations while also accounting for their own defense and national supremacy. The less powerful nations, who opposed these powers, were hoping to gain independence and freedom. The conflict came to a head in the Balkans of Eastern Europe. The Slavic people, who lived in the Balkan region and some of what is presently Serbia, felt they should have their own country. Serbia held a large Slavic population, but it was controlled and influenced by the Austria-Hungary Empire. Slavic nationalists were outraged by the invasion of Austria-Hungary, especially the annexation of Bosnia and Herzegovina. Young Slavic nationalists joined the “Black Hand ” group to oppose the Austria-Hungary Empire and its presumed heir, Archduke Franz Ferdinand.

The combination of the fuel of independence and nationalism was powerful, and the “Black Hand” group made a drastic decision that would change the direction of international relations forever – they assassinated the heir to the Austria-Hungary throne, Franz Ferdinand. The assassination of Archduke Frank Ferdinand by the Black Hand in Sarajevo directly led to the outbreak of World War I as nations scrambled to support their ally countries and vested interests abroad.

The essay on the causes of World War 1 highlighted that the four causes are closely related. A single reason is not enough to cause a Great War between several nations or between two alliances, though nationalism seems to be the most powerful. However, when these factors come together, they increase the possibility of war. Nationalism played the most important role in this because it led to military competition, land expansion, and cliques.

There were various factors that contributed to Germany’s decision to start WWI, including territorial ambitions, frustration with the Treaty of Versailles, and a belief in their own superiority. Germany sought to expand its empire and viewed itself as deserving of more power and land. Additionally, they presumed they could win the war quickly and simply, further fueling their desire to take action.

The primary causes of World War I were militarism, alliances, and imperialism. Militarism refers to the belief that a powerful military is crucial for a nation’s security. Alliances are pacts between nations to support each other in case of war. Imperialism denotes the desire to extend a nation’s authority and influence by acquiring additional territories.

To write about World War 1 in an essay, one must understand that it was a catastrophic global conflict that caused immense loss of life and lasted over four years. It commenced in 1914 following a chain of events that prompted various nations worldwide to mobilize their forces. Ultimately, the Allied Powers emerged triumphant over the Central Powers in 1918 to end the war.

What the data says about abortion in the U.S.

Pew Research Center has conducted many surveys about abortion over the years, providing a lens into Americans’ views on whether the procedure should be legal, among a host of other questions.

In a  Center survey  conducted nearly a year after the Supreme Court’s June 2022 decision that  ended the constitutional right to abortion , 62% of U.S. adults said the practice should be legal in all or most cases, while 36% said it should be illegal in all or most cases. Another survey conducted a few months before the decision showed that relatively few Americans take an absolutist view on the issue .

Find answers to common questions about abortion in America, based on data from the Centers for Disease Control and Prevention (CDC) and the Guttmacher Institute, which have tracked these patterns for several decades:

How many abortions are there in the U.S. each year?

How has the number of abortions in the u.s. changed over time, what is the abortion rate among women in the u.s. how has it changed over time, what are the most common types of abortion, how many abortion providers are there in the u.s., and how has that number changed, what percentage of abortions are for women who live in a different state from the abortion provider, what are the demographics of women who have had abortions, when during pregnancy do most abortions occur, how often are there medical complications from abortion.

This compilation of data on abortion in the United States draws mainly from two sources: the Centers for Disease Control and Prevention (CDC) and the Guttmacher Institute, both of which have regularly compiled national abortion data for approximately half a century, and which collect their data in different ways.

The CDC data that is highlighted in this post comes from the agency’s “abortion surveillance” reports, which have been published annually since 1974 (and which have included data from 1969). Its figures from 1973 through 1996 include data from all 50 states, the District of Columbia and New York City – 52 “reporting areas” in all. Since 1997, the CDC’s totals have lacked data from some states (most notably California) for the years that those states did not report data to the agency. The four reporting areas that did not submit data to the CDC in 2021 – California, Maryland, New Hampshire and New Jersey – accounted for approximately 25% of all legal induced abortions in the U.S. in 2020, according to Guttmacher’s data. Most states, though,  do  have data in the reports, and the figures for the vast majority of them came from each state’s central health agency, while for some states, the figures came from hospitals and other medical facilities.

Discussion of CDC abortion data involving women’s state of residence, marital status, race, ethnicity, age, abortion history and the number of previous live births excludes the low share of abortions where that information was not supplied. Read the methodology for the CDC’s latest abortion surveillance report , which includes data from 2021, for more details. Previous reports can be found at  stacks.cdc.gov  by entering “abortion surveillance” into the search box.

For the numbers of deaths caused by induced abortions in 1963 and 1965, this analysis looks at reports by the then-U.S. Department of Health, Education and Welfare, a precursor to the Department of Health and Human Services. In computing those figures, we excluded abortions listed in the report under the categories “spontaneous or unspecified” or as “other.” (“Spontaneous abortion” is another way of referring to miscarriages.)

Guttmacher data in this post comes from national surveys of abortion providers that Guttmacher has conducted 19 times since 1973. Guttmacher compiles its figures after contacting every known provider of abortions – clinics, hospitals and physicians’ offices – in the country. It uses questionnaires and health department data, and it provides estimates for abortion providers that don’t respond to its inquiries. (In 2020, the last year for which it has released data on the number of abortions in the U.S., it used estimates for 12% of abortions.) For most of the 2000s, Guttmacher has conducted these national surveys every three years, each time getting abortion data for the prior two years. For each interim year, Guttmacher has calculated estimates based on trends from its own figures and from other data.

The latest full summary of Guttmacher data came in the institute’s report titled “Abortion Incidence and Service Availability in the United States, 2020.” It includes figures for 2020 and 2019 and estimates for 2018. The report includes a methods section.

In addition, this post uses data from StatPearls, an online health care resource, on complications from abortion.

An exact answer is hard to come by. The CDC and the Guttmacher Institute have each tried to measure this for around half a century, but they use different methods and publish different figures.

The last year for which the CDC reported a yearly national total for abortions is 2021. It found there were 625,978 abortions in the District of Columbia and the 46 states with available data that year, up from 597,355 in those states and D.C. in 2020. The corresponding figure for 2019 was 607,720.

The last year for which Guttmacher reported a yearly national total was 2020. It said there were 930,160 abortions that year in all 50 states and the District of Columbia, compared with 916,460 in 2019.

• How the CDC gets its data: It compiles figures that are voluntarily reported by states’ central health agencies, including separate figures for New York City and the District of Columbia. Its latest totals do not include figures from California, Maryland, New Hampshire or New Jersey, which did not report data to the CDC. ( Read the methodology from the latest CDC report .)
• How Guttmacher gets its data: It compiles its figures after contacting every known abortion provider – clinics, hospitals and physicians’ offices – in the country. It uses questionnaires and health department data, then provides estimates for abortion providers that don’t respond. Guttmacher’s figures are higher than the CDC’s in part because they include data (and in some instances, estimates) from all 50 states. ( Read the institute’s latest full report and methodology .)

While the Guttmacher Institute supports abortion rights, its empirical data on abortions in the U.S. has been widely cited by  groups  and  publications  across the political spectrum, including by a  number of those  that  disagree with its positions .

These estimates from Guttmacher and the CDC are results of multiyear efforts to collect data on abortion across the U.S. Last year, Guttmacher also began publishing less precise estimates every few months , based on a much smaller sample of providers.

The figures reported by these organizations include only legal induced abortions conducted by clinics, hospitals or physicians’ offices, or those that make use of abortion pills dispensed from certified facilities such as clinics or physicians’ offices. They do not account for the use of abortion pills that were obtained  outside of clinical settings .

(Back to top)

The annual number of U.S. abortions rose for years after Roe v. Wade legalized the procedure in 1973, reaching its highest levels around the late 1980s and early 1990s, according to both the CDC and Guttmacher. Since then, abortions have generally decreased at what a CDC analysis called  “a slow yet steady pace.”

Guttmacher says the number of abortions occurring in the U.S. in 2020 was 40% lower than it was in 1991. According to the CDC, the number was 36% lower in 2021 than in 1991, looking just at the District of Columbia and the 46 states that reported both of those years.

(The corresponding line graph shows the long-term trend in the number of legal abortions reported by both organizations. To allow for consistent comparisons over time, the CDC figures in the chart have been adjusted to ensure that the same states are counted from one year to the next. Using that approach, the CDC figure for 2021 is 622,108 legal abortions.)

There have been occasional breaks in this long-term pattern of decline – during the middle of the first decade of the 2000s, and then again in the late 2010s. The CDC reported modest 1% and 2% increases in abortions in 2018 and 2019, and then, after a 2% decrease in 2020, a 5% increase in 2021. Guttmacher reported an 8% increase over the three-year period from 2017 to 2020.

As noted above, these figures do not include abortions that use pills obtained outside of clinical settings.

Guttmacher says that in 2020 there were 14.4 abortions in the U.S. per 1,000 women ages 15 to 44. Its data shows that the rate of abortions among women has generally been declining in the U.S. since 1981, when it reported there were 29.3 abortions per 1,000 women in that age range.

The CDC says that in 2021, there were 11.6 abortions in the U.S. per 1,000 women ages 15 to 44. (That figure excludes data from California, the District of Columbia, Maryland, New Hampshire and New Jersey.) Like Guttmacher’s data, the CDC’s figures also suggest a general decline in the abortion rate over time. In 1980, when the CDC reported on all 50 states and D.C., it said there were 25 abortions per 1,000 women ages 15 to 44.

That said, both Guttmacher and the CDC say there were slight increases in the rate of abortions during the late 2010s and early 2020s. Guttmacher says the abortion rate per 1,000 women ages 15 to 44 rose from 13.5 in 2017 to 14.4 in 2020. The CDC says it rose from 11.2 per 1,000 in 2017 to 11.4 in 2019, before falling back to 11.1 in 2020 and then rising again to 11.6 in 2021. (The CDC’s figures for those years exclude data from California, D.C., Maryland, New Hampshire and New Jersey.)

The CDC broadly divides abortions into two categories: surgical abortions and medication abortions, which involve pills. Since the Food and Drug Administration first approved abortion pills in 2000, their use has increased over time as a share of abortions nationally, according to both the CDC and Guttmacher.

The majority of abortions in the U.S. now involve pills, according to both the CDC and Guttmacher. The CDC says 56% of U.S. abortions in 2021 involved pills, up from 53% in 2020 and 44% in 2019. Its figures for 2021 include the District of Columbia and 44 states that provided this data; its figures for 2020 include D.C. and 44 states (though not all of the same states as in 2021), and its figures for 2019 include D.C. and 45 states.

Guttmacher, which measures this every three years, says 53% of U.S. abortions involved pills in 2020, up from 39% in 2017.

Two pills commonly used together for medication abortions are mifepristone, which, taken first, blocks hormones that support a pregnancy, and misoprostol, which then causes the uterus to empty. According to the FDA, medication abortions are safe  until 10 weeks into pregnancy.

Surgical abortions conducted  during the first trimester  of pregnancy typically use a suction process, while the relatively few surgical abortions that occur  during the second trimester  of a pregnancy typically use a process called dilation and evacuation, according to the UCLA School of Medicine.

In 2020, there were 1,603 facilities in the U.S. that provided abortions,  according to Guttmacher . This included 807 clinics, 530 hospitals and 266 physicians’ offices.

While clinics make up half of the facilities that provide abortions, they are the sites where the vast majority (96%) of abortions are administered, either through procedures or the distribution of pills, according to Guttmacher’s 2020 data. (This includes 54% of abortions that are administered at specialized abortion clinics and 43% at nonspecialized clinics.) Hospitals made up 33% of the facilities that provided abortions in 2020 but accounted for only 3% of abortions that year, while just 1% of abortions were conducted by physicians’ offices.

Looking just at clinics – that is, the total number of specialized abortion clinics and nonspecialized clinics in the U.S. – Guttmacher found the total virtually unchanged between 2017 (808 clinics) and 2020 (807 clinics). However, there were regional differences. In the Midwest, the number of clinics that provide abortions increased by 11% during those years, and in the West by 6%. The number of clinics  decreased  during those years by 9% in the Northeast and 3% in the South.

The total number of abortion providers has declined dramatically since the 1980s. In 1982, according to Guttmacher, there were 2,908 facilities providing abortions in the U.S., including 789 clinics, 1,405 hospitals and 714 physicians’ offices.

The CDC does not track the number of abortion providers.

In the District of Columbia and the 46 states that provided abortion and residency information to the CDC in 2021, 10.9% of all abortions were performed on women known to live outside the state where the abortion occurred – slightly higher than the percentage in 2020 (9.7%). That year, D.C. and 46 states (though not the same ones as in 2021) reported abortion and residency data. (The total number of abortions used in these calculations included figures for women with both known and unknown residential status.)

The share of reported abortions performed on women outside their state of residence was much higher before the 1973 Roe decision that stopped states from banning abortion. In 1972, 41% of all abortions in D.C. and the 20 states that provided this information to the CDC that year were performed on women outside their state of residence. In 1973, the corresponding figure was 21% in the District of Columbia and the 41 states that provided this information, and in 1974 it was 11% in D.C. and the 43 states that provided data.

In the District of Columbia and the 46 states that reported age data to  the CDC in 2021, the majority of women who had abortions (57%) were in their 20s, while about three-in-ten (31%) were in their 30s. Teens ages 13 to 19 accounted for 8% of those who had abortions, while women ages 40 to 44 accounted for about 4%.

The vast majority of women who had abortions in 2021 were unmarried (87%), while married women accounted for 13%, according to  the CDC , which had data on this from 37 states.

In the District of Columbia, New York City (but not the rest of New York) and the 31 states that reported racial and ethnic data on abortion to  the CDC , 42% of all women who had abortions in 2021 were non-Hispanic Black, while 30% were non-Hispanic White, 22% were Hispanic and 6% were of other races.

Looking at abortion rates among those ages 15 to 44, there were 28.6 abortions per 1,000 non-Hispanic Black women in 2021; 12.3 abortions per 1,000 Hispanic women; 6.4 abortions per 1,000 non-Hispanic White women; and 9.2 abortions per 1,000 women of other races, the  CDC reported  from those same 31 states, D.C. and New York City.

For 57% of U.S. women who had induced abortions in 2021, it was the first time they had ever had one,  according to the CDC.  For nearly a quarter (24%), it was their second abortion. For 11% of women who had an abortion that year, it was their third, and for 8% it was their fourth or more. These CDC figures include data from 41 states and New York City, but not the rest of New York.

Nearly four-in-ten women who had abortions in 2021 (39%) had no previous live births at the time they had an abortion,  according to the CDC . Almost a quarter (24%) of women who had abortions in 2021 had one previous live birth, 20% had two previous live births, 10% had three, and 7% had four or more previous live births. These CDC figures include data from 41 states and New York City, but not the rest of New York.

The vast majority of abortions occur during the first trimester of a pregnancy. In 2021, 93% of abortions occurred during the first trimester – that is, at or before 13 weeks of gestation,  according to the CDC . An additional 6% occurred between 14 and 20 weeks of pregnancy, and about 1% were performed at 21 weeks or more of gestation. These CDC figures include data from 40 states and New York City, but not the rest of New York.

About 2% of all abortions in the U.S. involve some type of complication for the woman , according to an article in StatPearls, an online health care resource. “Most complications are considered minor such as pain, bleeding, infection and post-anesthesia complications,” according to the article.

The CDC calculates  case-fatality rates for women from induced abortions – that is, how many women die from abortion-related complications, for every 100,000 legal abortions that occur in the U.S .  The rate was lowest during the most recent period examined by the agency (2013 to 2020), when there were 0.45 deaths to women per 100,000 legal induced abortions. The case-fatality rate reported by the CDC was highest during the first period examined by the agency (1973 to 1977), when it was 2.09 deaths to women per 100,000 legal induced abortions. During the five-year periods in between, the figure ranged from 0.52 (from 1993 to 1997) to 0.78 (from 1978 to 1982).

The CDC calculates death rates by five-year and seven-year periods because of year-to-year fluctuation in the numbers and due to the relatively low number of women who die from legal induced abortions.

In 2020, the last year for which the CDC has information , six women in the U.S. died due to complications from induced abortions. Four women died in this way in 2019, two in 2018, and three in 2017. (These deaths all followed legal abortions.) Since 1990, the annual number of deaths among women due to legal induced abortion has ranged from two to 12.

The annual number of reported deaths from induced abortions (legal and illegal) tended to be higher in the 1980s, when it ranged from nine to 16, and from 1972 to 1979, when it ranged from 13 to 63. One driver of the decline was the drop in deaths from illegal abortions. There were 39 deaths from illegal abortions in 1972, the last full year before Roe v. Wade. The total fell to 19 in 1973 and to single digits or zero every year after that. (The number of deaths from legal abortions has also declined since then, though with some slight variation over time.)

The number of deaths from induced abortions was considerably higher in the 1960s than afterward. For instance, there were 119 deaths from induced abortions in  1963  and 99 in  1965 , according to reports by the then-U.S. Department of Health, Education and Welfare, a precursor to the Department of Health and Human Services. The CDC is a division of Health and Human Services.

Support for legal abortion is widespread in many countries, especially in Europe

Nearly a year after roe’s demise, americans’ views of abortion access increasingly vary by where they live, by more than two-to-one, americans say medication abortion should be legal in their state, most latinos say democrats care about them and work hard for their vote, far fewer say so of gop, positive views of supreme court decline sharply following abortion ruling, most popular.
