Hurrian language
The Hurrians were a people who settled in northwestern Mesopotamia and southeast Anatolia in 1600 BC. By 1450 BC they established a medium-sized empire under a Mitanni ruling class, and temporarily made tributary vassals out of kings in the west, making them a major threat for the Pharaoh in Egypt until their overthrow by Assyria. The Hurrian language is related to the later Urartian, but there is no conclusive evidence these two languages are related to any others.
