Ra was the Egyptian sun god who was also often referred to as Re-Horakhty, meaning Ra (is) Horus of the Horizon, referring to the god's character. The early Egyptians believed that he created the world, and the rising sun was, for them, the symbol of creation. The daily cycle, as the sun rose, then set only to rise again the next morning, symbolized renewal and so Ra was seen as the paramount force of creation and master of life. His closest ally is Ma'at, the embodiment of order and truth.
Ra was also closely connected to the Pharaoh, Egypt's king. While the king ruled earth, Ra was the master of the universe so they were of the same nature and were in effect a mirror image of each other. Interestingly, up until the 2nd Dynasty, there is an absence of references on Ra, but his development began in the late 2nd Dynasty and matured through the 5th Dynasty. Ra became more and more associated with the king, who was both human and a god at once, embodied in the falcon named Horus and by the 4th Dynasty, referred to as the son of Ra. Hence, a relationship also developed between Horus and Ra as they were merged in the symbol of a winged sun disk, an icon that remained constant in Temples and religious monuments through the end of Egyptian history.
