List of U.S. Presidents: Terms, Parties, and Key Facts
The United States has had 46 individuals serve as president across 45 presidencies — Grover Cleveland is counted twice as the 22nd and 24th president, having served non-consecutive terms. This page catalogs each president, the party affiliation under which they served, the dates of their terms, and key constitutional or historical facts that define their administrations. For readers seeking deeper context on the structural powers these officeholders exercised, the full reference index provides access to the complete architecture of presidential authority.
Definition and scope
The presidency is established by Article II of the U.S. Constitution, which vests executive power in a single officer elected to a four-year term. Under the Twenty-Second Amendment, ratified in 1951, no individual may be elected president more than twice, nor serve more than ten years total under specific succession circumstances. Prior to that ratification, term limits were a matter of political convention rather than constitutional mandate — a convention broken by Franklin D. Roosevelt, who won four presidential elections between 1932 and 1944.
The scope of this list covers all 46 individuals who have held the office from George Washington's first inauguration on April 30, 1789 through the present constitutional framework. Political party designations reflect the party under which each president ran or was affiliated at the time of their election, recognizing that party names and platforms have shifted substantially across two centuries. For a detailed examination of how presidential term limits operate constitutionally, that topic is covered separately.
How it works
Presidential terms are set at four years each by Article II, Section 1 of the Constitution. A president may be removed before the term's end through impeachment and conviction (governed by Article I, Sections 2 and 3), death, resignation, or removal under the Twenty-Fifth Amendment disability procedures. Eight presidents have died in office — four by assassination and four by natural causes — and one, Richard Nixon, resigned in August 1974.

Common scenarios
Three recurring structural scenarios define how the list departs from the standard four-year elected sequence:
Succession upon death or resignation. Nine of the 46 individuals reached the office through succession rather than direct election — eight following the death of a predecessor and one (Gerald Ford) following resignation. These presidents exercised the same constitutional authority as elected presidents, a principle affirmed by the presidential succession order established under Article II and statutory law.
Non-consecutive terms. Grover Cleveland's two non-consecutive terms (1885–1889 and 1893–1897) produce the numerical anomaly of 46 individuals holding 45 distinct presidencies. No other person has replicated this pattern, though the Twenty-Second Amendment does not prohibit a former two-term president from seeking non-consecutive service — a constitutional question examined under presidential term limits.
Extended service beyond two terms. Franklin D. Roosevelt remains the only president to have served more than two terms, winning four consecutive elections. His unprecedented tenure directly prompted Congress to propose the Twenty-Second Amendment in 1947, which was ratified by 41 state legislatures by February 1951 (National Archives, Twenty-Second Amendment).
Decision boundaries
Party classification requires precision at two boundaries. First, the Federalist-to-Democrat-Republican-to-Democratic lineage reflects genuine discontinuities: the Democratic Party traces its founding to Andrew Jackson's coalition circa 1828, not to earlier Democratic-Republican predecessors. Second, the Republican Party was founded in 1854, and Abraham Lincoln became its first president in 1861 — meaning no president before Lincoln holds a Republican affiliation regardless of how earlier party alignments are described.
A comparative contrast worth noting: presidents who entered through succession (John Tyler, Andrew Johnson, Chester Arthur, Theodore Roosevelt, Calvin Coolidge, Harry Truman, Lyndon Johnson, Gerald Ford) faced distinct legitimacy and policy dynamics compared to elected presidents, even though their constitutional authority was identical. Theodore Roosevelt, Coolidge, Truman, and Lyndon Johnson each subsequently won election in their own right, while Tyler, Andrew Johnson, Arthur, and Ford did not. Ford is the sole individual to have held both the vice presidency and presidency without winning a national election for either office, having been appointed vice president under the Twenty-Fifth Amendment following Spiro Agnew's resignation in 1973.
