Hi!
What do you think the consequences would have been had Amenhotep IV not gone off the deep end and start a monotheistic cult? I read somewhere that he got the idea from his wife. All we need is a POD which has him marry someone else and there we go.
At the very minimum, Egypt doesn't get attacked as much as His Majesty spends more attention taking care of the country from the traditional capital instead of heading out to the boonies to build a new capital and pray. He seems to have been a pretty bright guy, so he could have been a good king.
His descendants (with a different wife God knows who'd have replaced Tutankhamen) probably wouldn't have had as many "counterrevolutionary" agendas. Who knows, part of the XVIIIth Dynasty might be butterflied away, and no Rameseses or people like that.
Come to think of it, if there's no Akhenaton to put monotheistic practices on the map (for good or ill), would it have still been available for the Hebrews to adopt in the time of Moses? Even if they did have a single god before they arrived in Egypt, they seemed to have been assimilated into Egyptian culture pretty well. So perhaps Judaism/Christianity/Islam get butterflied away.
