Mesopotamia
Major territorial states were the Akkadian kingdom, the Third Dynasty of Ur, and the Assyrian Empire. Some of the important historical Mesopotamian leaders were Ur-Nammu (king of Ur), Sargon of Akkad (the founder of the Akkadian kingdom), Hammurabi (who established the Old Babylonian state), and Tiglath-Pileser I (who started the Assyrian Empire).
