Amun-Ra retained chief importance in the Egyptian pantheon throughout the New Kingdom (with the exception of the "Atenist heresy" under Akhenaten).Amun-Ra in this period (16th to 11th centuries BC) held the position of transcendental, self-createdcreator deity "par excellence"; he was the champion of the poor or troubled and central to personal piety. His position as King of Gods developed to the point of virtual monotheism where other gods became manifestations of him. With Osiris, Amun-Ra is the most widely recorded of the Egyptian gods.
As the chief deity of the Egyptian Empire, Amun-Ra also came to be worshipped outside Egypt, according to the testimony of ancient Greek historiographers in Libya and Nubia. As Zeus Ammon, he came to be identified withZeus in Greece.
