Who was President during the Great Depression?

During the Great Depression, Franklin D. Roosevelt served as the President of the United States. He assumed office in March 1933, at a time when the nation was facing severe economic challenges. His administration introduced a series of programs and policies known as the New Deal, which aimed to provide relief for the unemployed, recover the economy, and reform the financial system to prevent future depressions. These initiatives played a significant role in shaping how the government interacted with the economy and provided support during tough times.

The other individuals listed were not in office during the Great Depression. Theodore Roosevelt, although a notable president, served earlier, and his presidency ended in 1909. Harry S. Truman took office after Franklin D. Roosevelt’s presidency, specifically following Roosevelt's death in 1945, which was well after the worst years of the Great Depression. Dwight D. Eisenhower was president in the 1950s, a time when the economy had largely recovered from the effects of the Great Depression. Thus, Franklin D. Roosevelt is the key figure associated with this critical period in American history.
