Which amendment limits a president to two terms?

The 22nd Amendment to the United States Constitution is the one that limits a president to two terms in office. This amendment was ratified in 1951 as a response to Franklin D. Roosevelt's four terms as president, which raised concerns about the potential for excessive accumulation of power in the executive branch. By instituting this limit, the amendment seeks to ensure a regular turnover in leadership and promote democratic ideals such as accountability and responsiveness to the electorate. The amendment clearly states that no person can be elected to the office of the President more than twice, thus establishing a clear legal guideline for presidential tenure. This foundational change reflects a key principle in American democracy, aiming to prevent any one individual from holding significant power for an extended period.
