Djedefre

Djedefre (also Djedefra and Radjedef) was an ancient Egyptian king (pharaoh) of the 4th Dynasty during the Old Kingdom. He ruled sometime in the middle of the 3rd Millennium BC. 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.

His name is said to mean "Enduring like Re" and his Horus name was Kheper which

is said to mean "Horus Appears". Based on the lost work Chronographiai by Sextus Julius Africanus (c. 160–240), possibly inspired by earlier work of Manetho (c. 290–260 BC), of which some later translations have survived it was early on suggested that the throne name of Djedefre was Ratoises.

Not to be confused with the 5th Dynasty ruler Djedkare Isesi.
