Akhenaten also  spelled Echnaton, Akhenaton, Ikhnaton, and Khuenaten; meaning "Effective for Aten"). He was known before the fifth year of his reign as Amenhotep IV (sometimes given its Greek form, Amenophis IV, and meaning Amun is Satisfied), was an Egyptian pharaoh who ruled for 17 years and died perhaps in 1336 BC or 1334 BC.

He is especially noted for abandoning traditional Egyptian polytheistic priesthood and introducing his own priesthood centered on a single god, Aten, which makes it the oldest recorded monotheistic religious system.

The majority of the Egyptian powers did not readily accept

Pharoah Aknenaten's religious changes.     After his death,the traditional priesthood gradually regained power and a dozen years later when a new dynasty was created, they discredited Akhenaten and his immediate successors, referring to Akhenaten himself as "the enemy" or "that criminal" in archival records.

The pharoah and his religious rebellion were all but lost to history until the discovery of the site of Akhetaten, the city he built for the Aten, at Amarna during the 19th century BC. Early excavations at Amarna created interest in the pharaoh, and a mummy found in the tomb KV55, unearthed in 1907 is likely that of Akhenaten. DNA analysis has determined that the man buried in KV55 is the father of the Pharoah Tutankhamun (King Tut)
