U.S. presidents

The President of the United States is the elected head of state and head of government of the United States. The president leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. The president is indirectly elected to a four-year term by the people through an Electoral College (or by the House of Representatives, should the Electoral College fail to award an absolute majority of votes to any person).

Since the office was established in 1789, 44 people have served as president. The first, George Washington, won a unanimous vote of the Electoral College. Grover Cleveland served two non-consecutive terms in office, and is counted as the nation's 22nd and 24th president. Thus the , Donald Trump, is the nation's 45th president. There are currently five living former presidents. The most recent death of a former president was on December 26, 2006 with the death of Gerald Ford; the most recently serving president to die was Ronald Reagan on June 5, 2004.

William Henry Harrison spent the shortest time in office, dying 31 days after taking office in 1841. Franklin D. Roosevelt served the longest, over twelve years, before dying early in his fourth term in 1945; he is the only president to have served more than two terms. Since the ratification of the Twenty-second Amendment to the United States Constitution in 1951, no person may be elected president more than twice, and no one who has served more than two years of a term to which someone else was elected may be elected more than once.
