limitation of number of terms a person can be president of the us
Many modern presidential republics employ term limits for their highest offices. The United States placed a limit of two terms on its presidency by means of the 22nd Amendment to the Constitution in 1951.
Section 1. No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of President more than once.
