 Also the campaigns into Amurru (modern Syria) and southern Mesopotamia may be responsible for the reintroduction of cuneiform writing into Anatolia, since the Hittite script is quite different from that of the preceding Assyrian Colonial period.Mursili continued the conquests of Hattusili I. Mursili's conquests reached southern Mesopotamia and even ransacked Babylon itself in 1531 BC (short chronology).Rather than incorporate Babylonia into Hittite domains, Mursili seems to have instead turned control of Babylonia over to his Kassite allies, who were to rule it for the next four centuries.
