World War I

Long-Term Causes of WWI

Immediate Causes of WWI

World War I began when all four factors—nationalism, alliances, imperialism, and militarism—violently intersected. During a tour of a Balkan province in the summer of 1914, the heir to the Austro-Hungarian throne and his wife were assassinated by Slav nationalists who wanted the province united with other southern Slavic nations. Austria-Hungary accused Serbia of supporting the terrorists and declared war. Russia sided with its Slavic client Serbia, while Germany pledged support for Austria-Hungary, its close Germanic ally. When Germany declared war on Russia, France honored its alliance and joined Russia. Great Britain, with no alliances, was the last major European power to enter the war, when German forces violated Belgium’s neutrality on their way to attack France.

The Great War

World War I, originally referred to as the Great War, was largely fought in Europe, but because of European economic and imperial dominion in much of the world at the time, there were secondary fronts in Africa, Asia, and on all the world’s oceans. Other factors made this war the greatest and worst the world had yet seen. Industrial progress had greatly increased the killing power of weaponry; artillery, machine guns, and mass-produced ammunition led to casualties in the millions. Armies were stalemated and took to trenches to survive, leading to a long cruel war of attrition to simply exhaust the enemy. The heroic notion of war was gone, and in crucial ways that played out over the rest of the century, Europe lost its self-assurance of being the world’s superior civilization.

This first total war mobilized entire nations. Civilians were crucial to the war effort, as industrial workers labored to provide armies with supplies. With so many men on the front lines, many women entered the workforce. Aircrafts bombed cities, and submarines tried to cut off food shipments. Governments controlled industry and agriculture and used propaganda to paint the enemy as evil.

In the end, Germany and the other Central Powers were unable to hold out against British, French, and American economic and military pressure, even after Russia had left the war and conceded eastern Europe to the Germans. Germany sued for an armistice in November, 1918.

The Treaty of Versailles

The peace conference to settle the issues stemming from the war was held near Paris at the Palace of Versailles. The leading Allied powers—Italy, Great Britain, France, and the United States—were labeled the “Big Four.” The European victors looked to increase their power at the expense of the defeated enemy. In contrast, U.S. President Woodrow Wilson entered the Versailles meetings with his plan, called the Fourteen Points. In it, he called for self-determination of nationalities, peace without victory, disarmament, fair treatment of colonial peoples, and the establishment of the League of Nations, a multinational organization for maintaining world peace.

In the end France, supported by Britain, would not allow the generous peace that Wilson had envisioned. Instead, the treaty laid down harsh terms to which Germany had to agree: one-sided blame and heavy reparations that would cripple the entire European economy. The map of Europe was redrawn at the expense of the German, Austro-Hungarian, and Russian Empires. New nations such as Poland, Czechoslovakia, Hungary, and Yugoslavia were all created in 1919 by the peace settlement. Although most of Wilson’s ideas were rejected, the League of Nations was approved. Ironically, the U.S. Congress opposed it and the United States did not join the idealistic new international order. The League was established in 1921, but without the great powers of America, Russia, or Germany (before 1926) as members it struggled to keep the peace when tensions arose.

The Treaty of Versailles was deeply flawed, as critics saw even at the time: it left many conflicts unresolved or even made worse. The imposition of war guilt and one-sided reparations on Germany, the economic powerhouse of central Europe, practically guaranteed a crippled recovery from the war’s devastation. Many colonized peoples complained that Wilson’s “self-determination” only applied to nations dominated by the defeated Central Powers. The worldwide British and French Empires continued to rule over millions of Africans and Asians.
