Black basalt sarcophagus in the funerary chamber of Unas' pyramid

Unas /ˈjuːnəs/ or Wenis, also spelled Unis (hellenized form Oenas /ˈiːnəs/ or Onnos), was an Ancient Egyptian pharaoh, the ninth and last ruler of the Fifth Dynasty during the Old Kingdom period. Unas reigned for 15 to 30 years in the mid-24th century BC succeeding Djedkare Isesi, who might have been his father. Little is known of Unas' activities during his reign, which was a time of economic decline. Egypt maintained trade relations with the Levantine coast and Nubia, and military action may have taken place in southern Canaan. The growth and decentralization of the administration in conjunction with the lessening of the king's power continued under Unas, ultimately contributing to the collapse of the Old Kingdom some 200 years later.
