The Twenty-second Amendment (Amendment XXII) 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, 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 (neither Alaska nor Hawaii had yet been admitted as a state), and its provisions came into force on that date.
The amendment prohibits anyone who has been elected president twice from being elected to the office again. Under the amendment, someone who fills an unexpired presidential term lasting more than two years is also prohibited from being elected president more than once. Scholars debate whether the amendment prohibits affected individuals from succeeding to the presidency under any circumstances or whether it applies only to presidential elections. Until the amendment's ratification, the president had not been subject to term limits, but both George Washington and Thomas Jefferson (the first and third presidents) decided not to run for a third term, establishing a two-term tradition. In the 1940 and 1944 presidential elections, Franklin D. Roosevelt became the only president to be elected for a third and fourth term, giving rise to concerns about a president serving unlimited terms.
