Babylonia was an ancient Akkadian-speaking state and cultural area based in the city of Babylon in central-southern Mesopotamia. 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", a deliberate archaism in reference to the previous glory of the Akkadian Empire. It was often involved in rivalry with the older ethno-linguistically related state of Assyria in the north of Mesopotamia and Elam to the east in Ancient Iran. Babylonia briefly became the major power in the region after Hammurabi 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.

Babylon was an ancient city located on the lower Euphrates river in southern Mesopotamia, within modern-day Hillah, Babil Governorate, Iraq about 85 kilometers south of modern day Baghdad. Babylon functioned as the main cultural and political centre of the Akkadian-speaking region of Babylonia. Its rulers establishing two important empires in antiquity, the 19th–16th century BC Old Babylonian Empire, and the 7th–6th century BC Neo-Babylonian Empire. Babylon was also used as a regional capital of other empires, such as the Achaemenid Empire. Babylon was one of the most important urban centres of the ancient Near East, until its decline during the Hellenistic period. Nearby ancient sites are Kish, Borsippa, Dilbat, and Kutha.
