After a series of military defeats in 1812–13, Napoleon was forced to abdicate the French throne on April 6, 1814. Napoleon returned to power in early 1815 but was again ousted on June 22, 1815. In October 1815 Napoleon was exiled to the remote island of St. Helena in the South Atlantic Ocean, where he remained until he died on May 5, 1821, at age 51.
