Who was the only U.S. President to serve four terms during the Great Depression and World War II?

Franklin D. Roosevelt is recognized as the only U.S. President to serve four terms, having been elected to the presidency four times from 1932 to 1944. His leadership during the tumultuous periods of the Great Depression and World War II was pivotal in shaping both domestic and foreign policy. Roosevelt's New Deal initiatives aimed to provide relief, recovery, and reform to the American economy affected by the Great Depression. Furthermore, his strategies and decisions during World War II had a profound impact on both the United States' involvement in the conflict and the post-war world order. Roosevelt's unprecedented four terms ultimately led to the 22nd Amendment, which established a two-term limit for future presidents, reflecting the transformative nature of his presidency.
