Babylonia (; Akkadian: , māt Akkadī) was an ancient Akkadian-speaking state and cultural area based in the city of Babylon in central-southern Mesopotamia (present-day Iraq and parts of Syria). It emerged as an Amorite-ruled state c. 1894 BC. During the reign of Hammurabi and afterwards, Babylonia was called "the country of Akkad" (Māt Akkadī in Akkadian), a deliberate archaism in reference to the previous glory of the Akkadian Empire. It was often involved in rivalry with the older state of Assyria to the north and Elam to the east in Ancient Iran. Babylonia briefly became the major power in the region after Hammurabi (fl. c. 1792–1752 BC middle chronology, or c. 1696–1654 BC, short chronology) created a short-lived empire, succeeding the earlier Akkadian Empire, Third Dynasty of Ur, and Old Assyrian Empire. The Babylonian Empire rapidly fell apart after the death of Hammurabi and reverted to a small kingdom. Like Assyria, the Babylonian state retained the written Akkadian language (the language of its native populace) for official use, despite its Northwest Semitic-speaking Amorite founders and Kassite successors, who spoke a language isolate, not being native Mesopotamians. It retained the Sumerian language for religious use (as did Assyria), but already by the time Babylon was founded, this was no longer a spoken language, having been wholly subsumed by Akkadian. The earlier Akkadian and Sumerian traditions played a major role in Babylonian and Assyrian culture, and the region would remain an important cultural center, even under its protracted periods of outside rule. History Pre-Babylonian Sumero-Akkadian period Mesopotamia had already enjoyed a long history prior to the emergence of Babylon, with Sumerian civilization emerging in the region c. 3500 BC, and the Akkadian-speaking people appearing by the 30th century BC. During the 3rd millennium BC, an intimate cultural symbiosis occurred between Sumerian and Akkadian-speakers, which included widespread bilingualism. The influence of Sumerian on Akkadian and vice versa is evident in all areas, from lexical borrowing on a massive scale, to syntactic, morphological, and phonological convergence. This has prompted scholars to refer to Sumerian and Akkadian in the third millennium as a sprachbund. Akkadian gradually replaced Sumerian as the spoken language of Mesopotamia somewhere around the turn of the third and the second millennium BC (the precise timeframe being a matter of debate). From c. 3500 BC until the rise of the Akkadian Empire in the 24th century BC, Mesopotamia had been dominated by
