William Henry Harrison, American general and politician, 9th President of the United States (died 1841)

William Henry Harrison was the ninth president of the United States, serving from March 4 to April 4, 1841, the shortest presidency in U.S. history. He was also the first U.S. president to die in office, causing a brief constitutional crisis, since presidential succession was not then fully defined in the U.S. Constitution. Harrison was the last president born as a British subject in the Thirteen Colonies. He was a member of the Harrison family of Virginia, a son of Benjamin Harrison V, who was a U.S. Founding Father; he was also the grandfather of Benjamin Harrison, the 23rd U.S. president.

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.
