Demetrius I Poliorcetes vs Eannatum

Demetrius commanded the Macedonian fleet to a decisive victory over Ptolemy I's navy off Salamis, Cyprus. He destroyed or captured much of the Ptolemaic fleet, allowing him to conquer Cyprus and establish a base for his father Antigonus I Monophthalmus.

Demetrius Poliorcetes besieged the city of Rhodes with massive siege engines, including the Helepolis, a 130-foot siege tower. After a year-long siege, he failed to capture the city and was forced to withdraw, but his innovative siege techniques earned him the epithet 'Poliorcetes' (Besieger of Cities).

After a period of chaos in Macedon, Demetrius seized the throne and was proclaimed king. He ruled Macedon for seven years, attempting to restore Antigonid power and launch campaigns to reclaim his father's empire in Asia.

After being defeated by Lysimachus and Pyrrhus, Demetrius fled to Asia Minor but was captured by Seleucus I. He was held in honorable captivity in Apamea, where he died three years later from illness and excessive drinking, ending his turbulent career.

Eannatum defeated the forces of Umma in a battle near the boundary canal between Lagash and Umma. The victory was commemorated on the Stele of the Vultures, which shows vultures carrying away the heads of the defeated. This established Lagash's dominance over Umma.

Eannatum, king of Lagash, commissioned the Stele of the Vultures, the first known historical document. The stele depicts his victory over Umma and records the boundary treaty between the two city-states. It is a key source for early Sumerian warfare and diplomacy.

Eannatum campaigned against Elam and Subartu, extending Lagash's influence beyond Sumer. Inscriptions record his victories and the tribute he exacted from these regions. This expansion made Lagash a major power in Mesopotamia during his reign.
