Babylonia (; Akkadian: 𒆳𒆍𒀭𒊏𒆠, māt Akkadī) was an ancient Akkadian-speaking state and cultural area based on the city of Babylon in central-southern Mesopotamia (present-day Iraq and parts of Syria). It emerged as an Akkadian-populated but Amorite-ruled state c. 1894 BC. During the reign of Hammurabi and afterwards, Babylonia was retrospectively 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 linguistically related state of Assyria in Upper Mesopotamia, and with Elam to the east. 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 centered around the city of Babylon.
Like Assyria, the Babylonian state retained the written Akkadian language for official use, despite its Northwest Semitic-speaking Amorite founders and Kassite successors, who spoke a language isolate. The state retained the Sumerian language in sacred texts for the Babylonian religion, but already by the time Babylon was founded, this was no longer a spoken language, having been replaced by Akkadian. The earlier Akkadian and Sumerian traditions played a major role in the descendant Babylonian culture, and the region would remain an important cultural center, even under its protracted periods of outside rule.
