The presidency of John Quincy Adams, began on March 4, 1825, when John Quincy Adams was inaugurated as President of the United States, and ended on March 4, 1829. Adams, the sixth United States president, took office following the 1824 presidential election, in which he and three other Democratic-Republicans—Henry Clay, William H. Crawford, and Andrew Jackson—sought the presidency. Adams was not a strong president, and he was under continuous attack from Jackson who easily defeated him in the 1828 presidential election.
