Who was the U.S. President during the Great Depression and World War II?

The U.S. President during the Great Depression and World War II was Franklin D. Roosevelt. He took office in March 1933, during the depths of the Great Depression, and implemented a series of programs known as the New Deal to address the economic crisis. These programs aimed to provide relief for the unemployed, recovery for the economy, and reform of the financial system.

Roosevelt's leadership extended into World War II, as he was President when the United States entered the war after the attack on Pearl Harbor in December 1941. He played a crucial role in rallying the American public and organizing the war effort against the Axis powers, working with other Allied leaders to achieve a successful outcome. His presidency marked a significant turning point in American history, as he guided the nation through two of its greatest challenges in the 20th century.

The other individuals listed served during different periods: Woodrow Wilson was President during World War I, Herbert Hoover was in office at the onset of the Great Depression but was succeeded by Roosevelt, and John F. Kennedy was President long after these events, specifically in the early 1960s.
