Well, I will be going into "fictional character" territory rather quickly - as per the latest update, Ishmael is Abraham's successor, and as a whole, Abraham's kingdom is much more militant in nature. As such, history of the Middle East will be wildly different - my idea is to have Abraham come up with religion, which is kind of like the "mandate of heaven" that ends up being picked up by numerous nations who may or may not have been related to the original Israelites.
Good point. Imagine the Hittites and Sea people thirsty for Human sacrifice. Nice TL idea.
