The following short video is an interesting discussion about the mysterious Mittani, a powerful society that seemed to vaporize into thin air. As I have mentioned on other threads, they married into the Egyptian royalty, making one wonder if this relates to the Abraham and Sarah adventure with the pharaoh. The alternative historian, Sweeney, believes that the Mittani (elites at least) became the later Medes that helped found the Persian Empire with Cyrus. The Mittani were also early adopters of chariots, and thus this makes them attractive candidates for being the Hyksos Shepherd Kings. Again, we're only concerned with the elites, as literal nomadic shepherds and such are of relatively little consequence.
