Follow Antigonus from veteran commander to the great rival of the other Diadochi.
Antigonus belonged to the senior Macedonian generation that had served in the wars of Philip II and Alexander. His nickname, Monophthalmus, means One-Eyed and reflects a wound remembered by later tradition. After Alexander's campaigns, Antigonus held authority in Asia Minor, a region rich in cities, routes, and strategic value. That base made him one of the most formidable figures after 323 BC.
As the first Successor wars unfolded, Antigonus expanded his authority across much of the Asian portion of Alexander's former empire. He was dangerous because he did not merely hold a province; he commanded armies and resources large enough to challenge the whole settlement. Other Successors feared that Antigonus wanted to restore unity under himself. Their alliances repeatedly formed around the need to contain him.
In 306 BC, after Demetrius defeated Ptolemy's forces near Cyprus, Antigonus and his son took the royal title. This was a turning point. It acknowledged openly what had already become true: Alexander's empire was no longer being governed for the Argead royal family. The Successors were kings in their own right. Antigonus moved first because he had the ambition and resources to claim the inheritance most boldly.
At Ipsus in 301 BC, a coalition of Successors defeated Antigonus and Demetrius. Antigonus, already an old man, died on the battlefield. His death ended the greatest attempt to reunite Alexander's empire under one Successor. His family's ambitions survived, however. The Antigonid dynasty eventually ruled Macedon, keeping his name central to the political map of the Hellenistic world.
