The 22nd Amendment to the United States Constitution was ratified on February 27, 1951, and limits the number of times a person can be elected to the office of President of the United States to two terms. The amendment also sets additional eligibility conditions for presidents who succeed to the office of President but have not been elected to it. The amendment was proposed by Congress in 1947, two years after the death of President Franklin D. Roosevelt, who had been elected to the presidency four times. The amendment was ratified by the legislatures of three-fourths of the several states within seven years from the date of its submission to the states by the Congress. Since the ratification of the 22nd Amendment, all subsequent presidents have served for no longer than two elected terms. Several attempts have been made by presidents and Congress members of many different political affiliations to either modify or outright repeal the 22nd Amendment.
