Alexandros II of Epirus

Alexander II (Greek: Άλέξανδρος) was a king of Epirus, and the son of Pyrrhus and Lanassa, the daughter of the Sicilian tyrant Agathocles.

Reign He succeeded his father as king in 272 BC, and continued the war which his father had begun with Antigonus II Gonatas, whom he succeeded in driving from the kingdom of Macedon. He was, however, dispossessed of both Macedon and Epirus by Demetrius II of Macedon, the son of Antigonus II; upon which he took refuge amongst the Acarnanians. By their assistance and that of his own subjects, who entertained a great attachment for him, he recovered Epirus. It appears that he was in alliance with the Aetolians.

Alexander married his paternal half-sister Olympias, by whom he had two sons, Pyrrhus ΙΙ, Ptolemy ΙΙ and a daughter, Phthia. Beloch places the death of King Alexander II "about 255", and supports this date with an elaborate chain of reasoning. On the death of Alexander, Olympias assumed the regency on behalf of her sons, and married Phthia to Demetrius.
