The term limit for a U.S. President is two terms, as established by the 22nd Amendment to the Constitution, ratified in 1951. This amendment was enacted in response to Franklin D. Roosevelt's four-term presidency, which raised concerns about the potential for increased consolidation of power. A president may serve a maximum of ten years if they assume the presidency via succession mid-term. This limit aims to promote democratic governance and prevent any individual from becoming too powerful in the nation's highest office, ensuring a regular opportunity for leadership transition.
