The Twenty-second Amendment to the United States Constitution, limiting Presidents to two terms, is ratified.

The Twenty-second Amendment 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 twice, 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, and its provisions came into force on that date.

The president of the United States (POTUS) is the head of state and head of government of the United States. The president directs the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces.
