Who was the President during both the Great Depression and World War II?

Franklin D. Roosevelt served as President of the United States during two major historical events: the Great Depression and World War II. He assumed the presidency in 1933, amidst the economic turmoil of the Great Depression, and implemented the New Deal programs to help revive the economy and provide relief to struggling Americans. Roosevelt’s leadership during this time helped shape modern American economic policy.

As World War II began, he was instrumental in leading the nation through the conflict after the attack on Pearl Harbor in 1941, until his death in 1945. His strategic decisions and ability to rally public support were crucial for the Allies' efforts in the war. Hence, his presidency is marked by these two significant and challenging periods in American history.
