Akhenaten, who was born Amenhotep IV, brought in a new era in Egypt when he ruled from 1352 BC to 1336 BC. He dismissed Egypt’s polytheism and introduced worship that focused solely on the Aten, the disc of the sun – which was considered heresy at the time. It was at this point that he changed his name from Amenhotep IV to Akhenaten, to honor Aten. Many experts say that by dismissing Egypt’s other gods, especially the main god, Amun, Akhenaten’s actions massively disrupted Egypt’s established power structure in the longstanding capital Thebes between the pharaoh’s court and the head temple priests.
