The royal inscriptions from Lagash also mention wars against other Lower Mesopotamian city-states, as well as against kingdoms farther away. Examples of the latter include Mari, Subartu, and Elam. These conflicts show that already in this stage in history there was a trend toward stronger states dominating larger territories. For example, king Eannatum of Lagash was able to defeat Mari and Elam around 2450 BC. Enshakushanna of Uruk seized Kish and imprisoned its king Embi-Ishtar around 2430. Lugal-zage-si, king of Uruk and Umma, was able to seize most of Lower Mesopotamia around 2450. This phase of warring city-states came to an end with the emergence of the Akkadian Empire under the rule of Sargon of Akkad.
