Piankhi (pēängˈkē, –ăngˈ–) [key], king of ancient Nubia (c.741–c.715 B.C.). After subduing Upper Egypt, he defeated (c.721 B.C.) Tefnakhte, lord of Saïs, who had just completed the conquest of Lower Egypt. Piankhi was also victorious at Memphis. He returned (c.718 B.C.) to his Nubian capital, Napata, and erected a granite stele on which he inscribed an account of his campaigns. Piankhi's rule in Egypt was too brief to achieve much; immediately after his withdrawal Tefnakhte reestablished his rule of Lower Egypt.
