About 1800 BC, Assyria came into conflict with the newly created city state of Babylon, which eventually eclipsed the far older Sumero-Akkadian states and cities in the south such as Ur, Isin, Larsa, Kish, Nippur, Eridu, Lagash, Umma, Uruk, Akshak and Adab, and incorporated them into a greater Babylonia. Assyria remained untroubled by the emergence of the Hittites and Mitanni, both to the north of Assyria, and by the Kassites who had seized Babylon from its Amorite founders. After securing its borders on all sides, Assyria entered into a quiet and peaceful period in its history which lasted for two and a half centuries. The emergence of the Mitanni Empire in c. 1600 BC did eventually lead to a short period of sporadic Mitannian-Hurrian domination in c. 1500 BC. The Indo-European-speaking Mitanni are thought to have conquered and formed the ruling class over the indigenous Hurrians of eastern Anatolia. The Hurrians spoke their own Hurrian language, that was neither Semitic nor Indo-European.
