The text rightly calls World War I the defining event of the twentieth century. The June 28, 1914, assassination of Archduke Francis Ferdinand, heir to the Austro-Hungarian Empire, by a Serbian terrorist, was the final spark. National rivalries were compounded by ethnic groups who had yet to secure their own “nation.” Social and class conflict led politicians to engage in foreign adventures to distract the masses. Conscript armies were ready. Perennial conflict in the Balkans threatened a wider war, given the tight-knit alliance systems. Austria, after receiving a “blank check” by Germany, declared war against Serbia on July 28. Germany declared war on Russia after the latter’s military mobilization. Germany’s Schlieffen Plan was to attack France through neutral Belgium. By August 4, the Great War had begun. Initially there was great enthusiasm. War gave excitement to ordinary lives, and most assumed that it would soon be over. The Germans drove the Russians back in the east, but in the west a stalemate developed, with trenches extending from the Swiss border to the English Channel, defended by barbed wire and machine guns. Attacking troops had to cross “no man’s land”: 21,000 British died on the first day of the Battle of the Somme. Artillery, poison gas, seasonal mud, and ever-present rats and decaying corpses added to the carnage.
The Ottoman Empire joined Germany, and Italy adhered to the Entente. After German submarine attacks, the United States entered the war in 1917. Conscription ensured a steady supply of soldiers. Governments took the economic lead, especially in producing munitions, and wage and price controls were instituted. Propaganda was employed to keep up morale, and newspapers were censored. Many women entered the labor force, and after the war were given the vote in the United States and Britain. Fortunes were made by some, but inflation hurt many.
Russia was unprepared for war, lacking a large industrial base or adequate leadership, and public support waned because of military losses. When bread rationing was introduced in March 1917, women demonstrated in the streets of St. Petersburg/Petrograd. The Duma established a Provisional Government and Nicholas abdicated on March 15. But socialist soviets, or workers’ councils, challenged the new government’s legitimacy. A faction of the Marxist Social Democrats was the revolutionary Bolsheviks of V.I. Lenin, who returned to Petrograd in April, where he campaigned for “Peace, Land, and Bread” and “All Power to the Soviets.” The war was increasingly unpopular, and in November the Bolsheviks seized power. Lenin established a dictatorship and signed a costly peace with Germany. Civil war broke out between the Bolshevik Reds and the Whites, who were unable to agree politically and militarily. Able military leaders, interior lines of defense, and “revolutionary terror” led the Bolsheviks to victory by 1921.
After Russia’s withdrawal from the war, Germany launched a massive attack in the west. However, the war had taken its toll in Germany, and in the fall, after American troops entered the conflict, the German government collapsed. On November 11, 1918, an armistice was signed. Riots occurred in Germany, but an attempted Bolshevik revolution failed. The peace delegates gathered at Paris in January 1919. Some, like America’s Woodrow Wilson, had idealistic hopes, including an association of nations to preserve the peace. Others wanted to punish Germany. The most important of five separate treaties was the Treaty of Versailles; Article 231 required Germany to accept guilt for causing the war and pay reparations. Its army was reduced to 100,000, and it lost territory to France and Poland. The Austrian and Ottoman empires were casualties of the war and the subsequent treaties. The United States refused to ratify the Treaty of Versailles and did not join the League of Nations, the institution that was to guarantee permanent peace.
