Under the rule of Hammurabi's successor Samsu-iluna , the short-lived Babylonian Empire began to collapse. In northern Mesopotamia, both the Amorites and Babylonians were driven from Assyria by Puzur-Sin a native Akkadian -speaking ruler, circa 1740 BC. Around the same time, native Akkadian speakers threw off Amorite Babylonian rule in the far south of Mesopotamia, creating the Sealand Dynasty , in more or less the region of ancient Sumer. Hammurabi's ineffectual successors met with further defeats and loss of territory at the hands of Assyrian kings such as Adasi and Bel-ibni , as well as to the Sealand Dynasty to the south, Elam to the east, and to the Kassites from the northeast. Thus was Babylon quickly reduced to the small and minor state it had once been upon its founding.  The coup de grace for the Hammurabi's Amorite Dynasty occurred in 1595 BC, when Babylon was sacked and conquered by the powerful Hittite Empire , thereby ending all Amorite political presence in Mesopotamia.  However, the Indo-European-speaking Hittites did not remain, turning over Babylon to their Kassite allies, a people speaking a language isolate , from the Zagros mountains region. This Kassite Dynasty was to rule Babylon for over 400 years, adopting parts of the Babylonian culture , including Hammurabi's code of laws. [ citation needed ]
