Khafre or Chephren was an ancient Egyptian monarch who was the fourth king of the Fourth Dynasty, during the earlier half of the Old Kingdom period. He was son of the king Khufu, and succeeded his brother Djedefre to the throne.
Khafre's enormous pyramid at Giza, the Pyramid of Khafre, is surpassed only by his father's. The Great Sphinx of Giza was also built for him, according to most Egyptologists. From Wikipedia
