Djedefre (also known as Djedefra and Radjedef) was an ancient Egyptian king (pharaoh) of the 4th Dynasty during the Old Kingdom. He is well known by the Hellenized form of his name Rhatoisēs (Ῥατοίσης) by Manetho. Djedefre was the son and immediate throne successor of Khufu, the builder of the Great Pyramid of Giza; his mother is not known for certain. He is the king who introduced the royal title Sa-Rê (meaning “Son of Ra”) and the first to connect his cartouche name with the sun god Ra. Family Djedefre married his brother Kawab's widow, Hetepheres II, who was sister to both of them, and who perhaps married a third brother of theirs, Khafre, after Djedefre's death. Another queen, Khentetenka is known from statue fragments in the Abu Rowash mortuary temple. Known children of Djedefre are: Hornit (“Eldest King's Son of His Body”) known from a statue depicting him and his wife. Baka (“Eldest King's Son”) known from a statue base found in Djedefre's mortuary temple, depicting him with his wife Hetepheres. Setka (“Eldest King's Son of His Body; Unique Servant of the King”) known from a scribe statue found in his father's pyramid complex. It is possible that he ruled for a short while after his father's death; an unfinished pyramid at Zawiyet el-Arian was started for a ruler whose name ends in ka; this could have been Setka or Baka. Neferhetepes (“King's Daughter of His Body; God's Wife”) is known from a statue fragment from Abu Rowash. Until recently, she was believed to be the mother of a pharaoh of the next dynasty, either Userkaf or Sahure. The French excavation team led by found the names of two other possible children of Djedefre in the pyramid complex: Nikaudjedefre (“King's Son of His Body”) was buried in Tomb F15 in Abu Rowash; it is possible that he wasn't a son of Djedefre but lived later and his title was only honorary. Hetepheres (“King's Daughter of His Body”) was mentioned on a statue fragment. Reign The Turin King List credits him with a rule of eight years, but the highest known year referred to during this reign appears to be the year of his 11th cattle count. The anonymous year of the 11th count date presumably of Djedefre was found written on the underside of one of the massive roofing-block beams which covered Khufu's southern boat-pits by Egyptian work crews.
