This Akhenaten chappy is generally accredited with being the first leader to impose a state-wide monotheistic religion, one that may have had lasting importance. It was a religion that although it lasted some twenty years may remarkably have a present-day significance. His works and ideas were dismantled and the Egyptians reverted to the old ways, but those same ideas may have found their way in to the Jewish and Christian traditions.
He does predate the monotheistic Judaism by around 200 years, and there are controversial theories of an evolution of his ideas in to Judaism, and one that argues that this Akhenaten chap may have been the Moses of the OT... but it is controversial stuff, much argued over by academics.
... but do know that some phrases from the inscriptions this Pharaoh had carved have found their way in to the Bible, particularly in to The Psalms.
