Ipsus

In central Phrygia (west-central Asia Minor), somewhere in the neighborhood of Synnada (perhaps the Roman Iullae, on the plain of the lower Akar Çayı)

The scene of one of the decisive engagements of the ancient world (301 BC), `the Battle of the Kings,’ fought between the successors of Alexander the Great: on the one side was Antigonus I Monophthalmos, aiming (with the assistance of his son Demetrius I Poliorcetes) to take over for himself Alexander's entire conquests; and confronting him were his rivals Lysimachus and Seleucus. Some 75,000 soldiers fought in the battle. After a successful cavalry charge, Demetrius continued to press ahead, thus exposing the flank of his father's infantry, which was routed by Seleucus' elephants; while Antigonus himself, waiting in vain for his son to return, was overwhelmed by a shower of missiles and perished. With him died the last possibility of a united Greek empire, and the epoch of separate Successor States had begun.
