The correct answer to this open question is the following.
Pharoh Akhenaten is an important figure from Egyptian history. Once he gained status as pharaoh, he wiped out the long-lasting, traditional
polytheistic order of religion and introduced Egypt (for a short time) to a monotheistic order based on the Sun-disk god, Atun.
Akhenaten (1353-1336 BCE) ruled as a Pharoh of the 18th dynasty and decided to install the honoring of the God Amun and put in practice a monotheist religion. This decision was not well accepted in ancient Egyptian society and this generated many problems for Akhenaten.
