Antigonid dynastyThe Antigonid dynasty was a dynasty of Macedonian kings ruling descended from Alexander the Great's general Antigonus I Monophthalmus ("the One-eyed"). Antigonus himself ruled mostly over Asia Minor and northern Syria. His attempts to take control of the whole of Alexander's empire led to his defeat and death at the Battle of Ipsus in 301 BC. Antigonus's son Demetrius I Poliorcetes survived the battle, and managed to seize control of Macedon itself a few years later, but eventually lost his throne, dying in prison. After a period of confusion, Demetrius's son Antigonus II Gonatas was able to establish the family's control over the old Kingdom of Macedon, as well as over most of the Greek city-states, by 276 BC.
