Refusing to acknowledge the previous two pharaohs, the first king of the 20th Dynasty dated the beginning of his reign to that of Seti II. He probably usurped the throne from Tausert, Seti IIs widow, and later queen-pharaoh. He was at an advanced age when he took the throne but managed to accomplish peace and order in a short period of time. His tomb was not completed when he died so he was placed in the tomb of Queen Tausert in the Valley of the Kings on the West Bank at Luxor (ancient Thebes). His coffin was found in Amenhotep II's tomb but his mummy has not been found. Setakht was the father of Ramesses III and the husband of Ramesses' mother, Tiye-merenese.
