Ra — also spelled Re — is the ancient Egyptian god of the sun, creation and kingship. He was one of the most important deities in the entire Egyptian pantheon, worshipped from the earliest dynasties through the Roman period. His primary cult centre was at Heliopolis (Egyptian: Iunu, "City of the Pillar"), near modern Cairo, where his priests maintained one of the oldest and most influential theological traditions in Egypt.
In Egyptian cosmology, Ra is not merely a god associated with the sun — he is the creative force itself, the first being who emerged from the primordial waters of Nun at the moment of creation. According to the Heliopolitan creation myth, Ra arose as the benben — the primordial mound, the first land to emerge from the waters of chaos — and then created the first gods through the power of his word, his breath and his self-generation. From Ra came Shu (air) and Tefnut (moisture), from them came Geb (earth) and Nut (sky), and from them came Osiris, Isis, Set and Nephthys — the great ennead of Heliopolis.
The Egyptians understood the sun not as a ball of burning gas but as Ra's eye — the visible manifestation of the god's creative and sustaining power. Each morning, Ra's emergence from the eastern horizon was the re-enactment of the original creation — the victory of light and order (Ma'at) over darkness and chaos (Isfet). Each night, Ra's descent into the western horizon was his journey into the Duat — the Egyptian underworld — where he faced the chaos serpent Apophis in a battle that had to be won anew every night to ensure the sun would rise again.
Ra was also the divine father of the pharaoh. The pharaoh was understood as the "Son of Ra" — the earthly representative of the solar creative force, responsible for maintaining Ma'at (cosmic order) in the human realm just as Ra maintained it in the cosmic realm. This theological identification of kingship with solar divinity was one of the most enduring features of Egyptian civilisation, persisting in various forms for over three thousand years.
