Ipsus
Ipsus is the site of a pivotal battle in ancient history, known as the Battle of Ipsus, fought in 301 BC in central Phrygia, near modern-day Synnada in Turkey. This battle was a significant confrontation among the Diadochi, the successors of Alexander the Great, primarily involving Antigonus I Monophthalmos and his son Demetrius I Poliorcetes against the rival leaders Lysimachus and Seleucus. Approximately 75,000 soldiers participated in this fierce engagement, marking it as one of the most consequential military encounters of the ancient world.
The battle is notable for its tactical maneuvers, including a crucial cavalry charge by Demetrius that ultimately led to the downfall of Antigonus's forces. The defeat of Antigonus not only resulted in his death but also extinguished the last hopes of reuniting Alexander's vast empire, leading to the establishment of distinct successor states. The outcome at Ipsus had lasting implications for the political landscape of the Hellenistic world, shaping the future of the region and influencing the course of history following Alexander's empire.

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.
