The Antigonid dynasty is named after Antigonos I Monophthalmos, who was a general under Alexander the Great. Together with his son, Demetrios I Poliorketes, he grew to be a major thorn in the side of the rest of the diadochi and became so powerful that it required a concerted effort from all of them to take him down.
After their defeat and Antigonos’ death in the Battle of Ipsos in 301 BCE, Demetrios headed the monarchy. He eventually took control of Macedon, but not long after he was taken prisoner by Seleukos I Nikator.
It was Demetrios’ son Antigonos II Gonatas who eventually provided some normalcy to the line. He eventually took control of Macedon and passed it on to his son, Demetrios II.
It then went to Antigonos III Doson, Philip V, and finally Perseus before the Antigonid line ended with the crushing of Macedon by Rome.
