Which U.S. President led the country during the Great Depression and World War II?

Franklin Roosevelt is recognized for his leadership during two of the most significant events in American history: the Great Depression and World War II. He served as President from 1933 until his death in 1945, implementing the New Deal programs aimed at recovering from the economic turmoil of the Great Depression. These programs focused on providing relief for the unemployed, recovering the economy, and reforming the financial system to prevent future depressions.

As the country entered World War II, Roosevelt played a crucial role in mobilizing the nation for war, establishing alliances with other nations, and shaping U.S. military strategy. His leadership helped lead the Allies to victory, and his policies significantly reshaped the role of the U.S. in both domestic and international spheres.

In contrast, Theodore Roosevelt served long before these events, primarily in the early 20th century, Harry Truman assumed the presidency after Roosevelt's death in 1945 and guided the country through the end of World War II and the onset of the Cold War, and Dwight D. Eisenhower became president later, during the 1950s. Thus, none of these three presidents were in charge during the pivotal times that Franklin Roosevelt navigated.
