The United States entered World War I in 1917 after a series of events that ultimately forced President Woodrow Wilson to abandon his initial stance of neutrality. The sinking of the Lusitania, a British passenger liner, by a German submarine in 1915, was a pivotal moment in the shift towards American involvement. The Lusitania carried over 100 American citizens, and the tragedy sparked outrage and anti-German sentiment across the nation. Germany initially agreed to stop unrestricted submarine warfare, which targeted all ships, including those carrying civilians, in an attempt to appease the United States. However, in 1917, Germany resumed its unrestricted submarine warfare, sinking six American ships and escalating tensions.

The Zimmerman Telegram, intercepted by British intelligence and released to the American public, further fueled the flames of war. This coded message from Germany to Mexico proposed an alliance, promising Mexico the return of territories lost to the United States in the Mexican-American War, if Mexico would declare war on the United States. The telegram, which was seen as a direct threat to American sovereignty, solidified public opinion in favor of war.

The war had a significant impact on American society, both domestically and internationally. The Great Migration, a mass movement of African Americans from the rural South to the industrial North, began during the war. Driven by economic opportunities and a desire to escape racial discrimination in the South, African Americans sought jobs in factories and shipyards that were experiencing labor shortages due to the war effort. The war also led to the passage of the Espionage Act in 1917, which made it illegal to interfere with the war effort, including speaking out against the war or obstructing recruitment. This act was used to suppress dissent and silence critics of the war, including socialist Eugene V. Debs, who was arrested and sentenced to ten years in prison for delivering an anti-war speech.

Following the war, President Wilson proposed his Fourteen Points, a plan for a just and lasting peace. These points included the establishment of a League of Nations, an international organization designed to prevent future wars through diplomacy and collective security. However, the United States ultimately did not join the League of Nations, a decision that reflected the isolationist sentiment that prevailed in the country after the war. The debate over the League of Nations highlighted the deep divisions within American society about the role of the United States in international affairs.

The end of World War I marked a turning point in American history, ushering in a period of significant social and cultural change. The Eighteenth Amendment, which prohibited the manufacture, sale, and transportation of alcoholic beverages, was ratified in 1919, reflecting the growing influence of the temperance movement. The Nineteenth Amendment, which granted women the right to vote, was ratified in 1920, marking a major victory for the women's suffrage movement. These amendments, along with other social and cultural developments, contributed to the emergence of a new national identity in the United States, one that was characterized by a sense of optimism, prosperity, and cultural experimentation.
