Akhenaten was a pharaoh of Ancient Egypt who ruled from 1353 to 1336 BC. He is also known as Amenhotep IV. Akhenaten is known for his religious reforms, which involved the worship of a single god, Aten, the sun deity. This was a significant departure from the traditional polytheistic religion of Ancient Egypt, which worshipped many gods and goddesses. Akhenaten's religious reforms were not well-received by the people, and after his death, the traditional religion was restored.
