Despotie ruler of the Philippines for 21 years ending 1986?

This was President Ferdinand Marcos, who took power in 1965. After he was deposed, the new President was Corazon Aquino, widow of the former opposition leader Begnino S. Aquino, who Marcos had assassinated in 1984. Marcos fled into exile, and died in 1990, although his widow Imelda is still alive and has since returned to the Phillippines.
