Antigonus I Monophthalmus
The Babylonian War was a conflict fought between 311–309 BC between the Diadochi kings Antigonus I Monophthalmus and Seleucus I Nicator, ending in a victory for the latter, Seleucus I Nicator. The conflict ended any possibility of restoration of the empire of Alexander the Great, a result confirmed in the Battle of Ipsus.
