President Franklin D. Roosevelt faced numerous challenges during his presidency, particularly during the Great Depression and World War II. Upon taking office in 1933, he implemented the New Deal programs to combat economic turmoil, addressing issues like unemployment, banking reform, and infrastructure development. The effectiveness of his policies was often met with criticism and opposition from various political factions. During World War II, Roosevelt navigated complex global tensions, leading the U.S. into the conflict after the attack on Pearl Harbor in 1941. His leadership in both crises reshaped American society and the role of government in economic recovery and international relations.
