Akhenaten was an Egyptian pharaoh who famously shifted the religious focus from traditional polytheism to Atenism, the worship of the sun disc Aten. He ruled during the Eighteenth Dynasty. Imagine him as the Steve Jobs of ancient Egypt, completely revolutionizing the system. He moved the capital to Akhetaten (Amarna) and promoted a new artistic style. His reign was a period of significant change and religious upheaval, though his changes were largely reversed after his death.
