== History of the United States (1917–1945) ==

The history of the United States from 1917 to 1945 covers the period of American history that includes the end of World War I, the Roaring Twenties, the Great Depression, and World War II. This era was marked by significant social, economic, and political changes that shaped the modern United States.

World War I (1917-1918)

The United States entered World War I in April 1917, joining the Allied Powers against the Central Powers. The U.S. mobilized over four million military personnel and played a crucial role in the final year of the war. The Treaty of Versailles was signed in 1919, officially ending the war.

The Roaring Twenties

The 1920s, often referred to as the Roaring Twenties, was a decade of economic prosperity and cultural change. The period saw the rise of jazz music, the Harlem Renaissance, and significant advancements in technology and industry. The Prohibition era began in 1920 with the ratification of the Eighteenth Amendment, banning the sale, production, and transportation of alcoholic beverages.

The Great Depression

The Great Depression was a severe worldwide economic downturn that began in 1929 and lasted until the late 1930s. The Stock Market Crash of 1929 marked the beginning of the Depression, leading to widespread unemployment, poverty, and economic hardship. President Franklin D. Roosevelt implemented the New Deal, a series of programs and reforms aimed at economic recovery and social welfare.

World War II (1939-1945)

The United States initially remained neutral during the early years of World War II. However, the attack on Pearl Harbor by Imperial Japan on December 7, 1941, led to the U.S. declaring war on Japan and subsequently on Nazi Germany and Fascist Italy. The U.S. played a significant role in the Allied victory, contributing to major military campaigns in both the European and Pacific theaters. The war ended in 1945 with the unconditional surrender of the Axis powers.
