Kazakhstan is on the east side of the Caspian Sea, and at least as far as academic/accepted/censored history goes, Khazaria was on the west side of the Caspian Sea centered on the Caucasus Mountain range wedged between Russia and the Middle East. The Khazars controlled the trade of the Middle East, India, and to some extent China with eastern Europe and modern western Russia. So it was a very strategic spot and they were the worst of the worst so naturally their enemies grew tired of their antics and attempted to wipe them out. The conspiracy theory goes that they moved west over time with each cycle of financial trickery they gainied power only to go incognito after people wised up and realized the enemy. If the theory is true then to some extent this would explain the spread of jews across Europe resulting in a people without a homeland whether they realized their genesis or not. So the Khazars could have originated in the Kazakhstan area before moving and setting up shop in "Khazaria", and they could have been somewhere before Kazakhstan and before that and so on. That archetype of exploiting one land and then moving on to the next could really have its corporate roots in the Khazars and everything since has been the work of utilizing numerous franchises to take over the world in secrecy.
