Franklin D. Roosevelt served as the longest-tenured president of the United States, holding office for over 12 years from 1933 to 1945.

Elected to an unprecedented four terms, Roosevelt led the nation through the Great Depression and the majority of World War II. His tenure saw significant changes in American government and society, including the implementation of the New Deal programs aimed at economic recovery.

Roosevelt's leadership during these critical times left a lasting impact on the country, and his extended presidency eventually led to the 22nd Amendment, which limits presidents to two terms in office.
