Which amendment allows a President to be elected to only two terms and to serve for no more than 10 years?

The 22nd Amendment to the United States Constitution specifically limits a person to being elected to the office of President for no more than two terms. This amendment was ratified in 1951 in response to Franklin D. Roosevelt's four terms in office. It also stipulates that if a person who has served more than two years of a term to which someone else was elected cannot be elected to more than one additional full term. This means that a President could serve a maximum of 10 years in total under certain circumstances. The intention behind the amendment is to ensure a rotation in leadership and prevent any one individual from holding too much power for an extended period. This legislative change reflected concerns about the potential for executive overreach and the importance of regular democratic turnover in the highest office of the land.
