who was believed to be the son of re the sun god
Ra His local cult began to grow from roughly the second dynasty, establishing Ra as a sun deity. By the Fourth Dynasty, pharaohs were seen as Ra's manifestations on earth, referred to as "Sons of Ra". His worship increased massively in the Fifth Dynasty, when Ra became a state deity and pharaohs had specially aligned pyramids, obelisks, and solar temples built in his honor. The rulers of the Fifth Dynasty told their followers that they were sons of Ra himself and the wife of the high priest of Heliopolis.[4] These pharaohs spent most of Egypt's money on sun temples.[4] The first Pyramid Texts began to arise, giving Ra more and more significance in the journey of the pharaoh through the Underworld.[4]
