The Lost Civilization Of The Sumerians

  This greatly upset the balance of power within the region, weakening the areas where Sumerians was spoken, and comparatively strengthening those where Akkadian was the major language. Henceforth, Sumerian would remain only a literary and liturgical language, similar to the position occupied by Latin in medieval Europe. Following an Elamite invasion and sack of Ur during the rule of Ibbi-Sin (c. 2028–2004 BC),[citation needed] Sumer came under Amorite rule (taken to introduce the Middle Bronze Age). The independent Amorite states of the 20th to 18th centuries are summarized as the "Dynasty of Isin" in the Sumerian king list, ending with the rise of Babylonia under Hammurabi c. 1800 BC. Later rulers who dominated Assyria and Babylonia occasionally assumed the old Sargonic title "King of Sumer and Akkad", such as Tukulti-Ninurta I of Assyria after c. 1225 BC.
