Longest Term President in the United States

The need for steady leadership during World War II (1939-1945) made it possible for Democrat Franklin Delano Roosevelt to break the tradition by winning four successive elections between 1932 and 1944. In a reaction against Franklin Roosevelt’s extended presidency, in 1951 Congress and state legislatures approved the 22nd Amendment to the Constitution, which limits a president to two elected terms. The amendment also prohibits a person from running for election a second time if he or she has already served more than two years of a term to which someone else had been elected.
