The Twenty-second Amendment to the United States Constitution limits the number of times a person can be elected to the office of President of the United States to two terms, and sets additional eligibility conditions for presidents who succeed to the unexpired terms of their predecessors. Congress approved the Twenty-second Amendment on March 21, 1947, and submitted it to the state legislatures for ratification. That process was completed on February 27, 1951, when the requisite 36 of the 48 states had ratified the amendment, and its provisions came into force on that date.

Franklin Delano Roosevelt, commonly known by his initials FDR, was an American statesman and politician who served as the 32nd president of the United States from 1933 until his death in 1945. He was a member of the Democratic Party and is the only U.S. president to have served more than two terms. His initial two terms were centered on combating the Great Depression, while his third and fourth saw him shift his focus to America's involvement in World War II.
