How WWI Changed America: America Goes to War

Europe on the Brink and America's Initial Neutrality00:00:03

Europe, after decades of peace, entered World War I in 1914 following the assassination of Archduke Franz Ferdinand. The conflict quickly escalated, with the Central Powers (Germany, Austro-Hungarian, Ottoman Empires) against the Allied powers (Britain, France, Russia). Despite personal tragedy, President Woodrow Wilson declared America's neutrality, hoping to avoid internal divisions and believing the war would be short-lived.

Economic Involvement and the Path to War00:01:11

As the war prolonged, European powers sought financial and material aid from the United States. America primarily provided loans, munitions, and supplies to the Allied side. German U-boat attacks, notably the sinking of the Lusitania in 1915, heightened tensions. Germany, in early 1917, gambled on unrestricted submarine warfare, believing they could win before the US could effectively intervene, leading to them sinking American ships.

America Declares War and Military Expansion00:02:48

In early 1917, continued German attacks on American ships compelled President Wilson to ask Congress for a declaration of war. The US military, initially small, underwent rapid expansion through conscription, growing from 300,000 to over four million men within 19 months. The monumental task involved training, equipping, transporting, and supplying this massive force almost from scratch.

Impact of American Intervention and Allied Victory00:03:47

By June 1918, a significant American army was in Europe, with 850,000 soldiers on the continent by fall, comparable to the British forces. Although the US anticipated the war continuing until 1920, the German army surrendered in October 1918, unable to withstand the combined Allied pressure. American entry provided a crucial turn of the tide and a psychological boost, contributing to the ultimate Allied victory.
