The last chance to reunite the Alexandrine Empire had already been passed when Antigonus lost the Babylonian War and two thirds of his empire. Ipsus confirmed this failure. As Paul K. Davis writes, "Ipsus was the high point of the struggle among Alexander the Great’s successors to create an international Hellenistic empire, which Antigonus failed to do." Instead, the empire was carved up between the victors, with Ptolemy retaining Egypt, Seleucus expanding his power to eastern Asia Minor, and Lysimachus receiving the remainder of Asia Minor. Eventually Seleucus would defeat Lysimachus at the Battle of Corupedium in 281 BC, but he was assassinated shortly afterward. Ipsus finalized the breakup of an empire, which may account for its obscurity; despite that, it was still a critical battle in classical history and decided the character of the Hellenistic age.
