Eannatum

Eannatum was a Sumerian king of Lagash who established one of the first verifiable empires in history. One inscription of his, found on a boulder, states that Eannatum was his Sumerian name, while his "Tidnu" (Amorite) name was Lumma.

Conquest of Sumer

Eannatum, grandson of Ur-Nanshe, was a king of Lagash who conquered all of Sumer, including Ur, Nippur, Akshak (controlled by Zuzu), Larsa, and Uruk (controlled by Enshakushanna, who is on the King List). He also annexed the kingdom of Kish, which regained its independence after his death. He made Umma a tributary, where every person had to pay a certain amount of grain into the treasury of the goddess Nina and the god Ingurisa after personally commanding an army to subjugate the city.

Conquest outside Sumer

Eannatum expanded his influence beyond the boundaries of Sumer. He conquered parts of Elam, including the city Az off the coast of the modern Persian Gulf, allegedly smote Shubur, and demanded tribute as far as Mari. However, often parts of his empire were revolting. During Eannatum’s reign, many temples and palaces were built, especially in Lagash. The city of Nina, probably a precursor of Niniveh, was rebuilt, with many canals and reservoirs being excavated.
