 In 1940, Franklin D. Roosevelt (president, 1933–1945) became the only president to break the tradition, winning a third term in 1940 and a fourth term in 1944.This gave rise to a successful move to formalize the traditional two-term limit by amending the U.S. Constitution.As ratified in 1951, the Twenty-Second Amendment provides that "no person shall be elected to the office of President more than twice".
