Taharka (təhärˈkə) [key] or Tirhakah tērˈəkə, tērhäˈkə, d. 663 B.C., king of ancient Egypt, last ruler of the XXV dynasty; son of Piankhi. Before he was king, he led the Egyptians against Sennacherib, who disastrously defeated him. Seizing (688 B.C.) the throne by force, Taharka established a residence at Tanis. In 671 he lost Memphis and Lower Egypt to the Assyrians under Esar-Haddon. On the withdrawal of the Assyrians, Taharka again entered Lower Egypt, only to be expelled (667) by Assurbanipal. He restored the temples at Napata.
