In Egyptian mythology, Amun was regarded as the king of the gods in Thebes.
Amun began as a deity associated with hiddenness and was worshipped in connection with the Hermopolitan Ogdoad. His importance grew dramatically when Thebes became the base of rulers who reunified Egypt after the Second Intermediate Period. By the New Kingdom, Amun had become the city’s patron and a national state god.
At Karnak, Amun was worshipped alongside his consort Mut and their son Khonsu in the Theban Triad. He was also fused with the solar god Ra to form Amun-Ra, combining Theban political power with older solar kingship traditions. Pharaohs credited Amun with military victories and funded enormous temple estates in his honor.
A common mix-up is Ra, who was the major solar and royal deity, or Ptah, whose main center was Memphis. Amun’s defining association in this question is Thebes. His influence later extended into Nubia, where Amun was worshipped at places such as Jebel Barkal, and Greek writers identified him with Zeus.
