World War I and America

World War I, which lasted from 1914 to 1918, had a profound impact on America, as the country transitioned from a position of neutrality to active involvement in the conflict. The United States entered the war in 1917, driven by factors such as unrestricted submarine warfare by Germany and the Zimmermann Telegram, which revealed Germany's attempts to persuade Mexico to join the war against the U.S. American soldiers, known as 'doughboys,' played a critical role in the Allied victory, contributing to the eventual defeat of the Central Powers. The war also led to significant social changes at home, including the Great Migration of African Americans to northern cities for work in wartime industries and the advancement of women's rights as they filled roles traditionally held by men during the war. The aftermath of World War I set the stage for major political and social changes in the United States, including the Red Scare and the eventual push for the Roaring Twenties.
