Franklin D. Roosevelt was the President of the United States during both the Great Depression and World War II. He assumed office in 1933, at the height of the Great Depression, and led the nation through significant economic recovery efforts with his New Deal programs. Roosevelt was then re-elected multiple times and guided the country through World War II until his death in 1945. His leadership spanned from addressing the domestic economic crisis to managing the global conflict, making him the only U.S. president to serve more than two terms and the key figure during these two critical periods in American history
