Kassite dynasty was established in Babylonia. Kassite dynasty, 1595–1155 BC The Kassite dynasty was founded by Gandash of Mari. The Kassites, like the Amorite rulers who had preceded them, were not originally native to Mesopotamia. Rather, they had first appeared in the Zagros Mountains of what is today northwestern Iran. The ethnic affiliation of the Kassites is unclear. Still, their language was not Semitic or Indo-European, and is thought to have been either a language isolate or possibly related to the Hurro-Urartian language family of Anatolia, although the evidence for its genetic affiliation is meager due to the scarcity of extant texts. That said, several Kassite leaders may have borne Indo-European names, and they may have had an Indo-European elite similar to the Mitanni elite that later ruled over the Hurrians of central and eastern Anatolia. The Kassites renamed Babylon Karduniaš and their rule lasted for 576 years, the longest dynasty in Babylonian history. This new foreign dominion offers a striking analogy to the roughly contemporary rule of the Hyksos in ancient Egypt. Most divine attributes ascribed to the Amorite kings of Babylonia disappeared at this time; the title "god" was never given to a Kassite sovereign. Babylon continued to be the capital of the kingdom and one of the holy cities of western Asia, where the priests of the ancient Mesopotamian religion were all-powerful, and the only place where the right to inheritance of the short lived old Babylonian empire could be conferred. Babylonia experienced short periods of relative power, but in general proved to be relatively weak under the long rule of the Kassites, and spent long periods under Assyrian and Elamite domination and interference. It is not clear precisely when Kassite rule of Babylon began, but the Indo-European Hittites from Anatolia did not remain in Babylonia for long after the sacking of the city, and it is likely the Kassites moved in soon afterwards. Agum II took the throne for the Kassites in 1595 BC, and ruled a state that extended from Iran to the middle Euphrates; The new king retained peaceful relations with Erishum III, the native Mesopotamian king of Assyria, but successfully went to war with the Hittite Empire, and twenty-four years after, the Hittites took the sacred statue of Marduk, he recovered it and declared the god equal to the Kassite deity Shuqamuna. Burnaburiash I succeeded him and drew up a peace treaty with
