Term limits in the Constitution in contrast to the Articles of Confederation, the federal constitution convention at Philadelphia omitted mandatory term limits from the second national frame of government, i.e. the U.S. Constitution of 1787 to the present. Nonetheless, largely because of grassroots support for the principle of rotation, rapid turnover in Congress prevailed. Also, George Washington set the precedent for a two-term tradition that prevailed (with the exception of Franklin Delano Roosevelt's four terms) until the 22nd Amendment of 1951.
However, when the states ratified the Constitution (1787–88), several leading statesmen regarded the lack of mandatory limits to tenure as a dangerous defect, especially, they thought, as regards the Presidency and the Senate.
