whom were forsaken by their men, she is obliged to surrender, 316. Cassander, having caused her to be condemned by the Macedonian people, has her put to death. 4. Cassander being now master, and, from 302, king of Macedonia, confirmed his dominion by a marriage with Thessalonice, half-sister to Alexander, and at the same time endeavoured to corroborate as far as possible his authority in Greece. Polysperchon and his son Alexander, it is true, still made head in Peloponnesus; but the states without the peninsula, Aetolia excepted, were all either allies of Cassander, or occupied by Macedonian troops. After the defeat of the league against Antigonus, in which Cassander had borne a part, general peace was concluded, with the proviso, that the Grecian cities should be free, and that the young Alexander, when of age, should be raised to the throne of Macedonia: this induced Cassander to rid himself both of the young prince and his mother Roxana by murder: but he thereby exposed himself to an attack from Polysperchon, who, availing himself of the discontent of the Macedonians, brought back Hercules, the only remaining illegitimate son of Alexander. Cassander diverted the storm by a new crime, instigating Polysperchon to murder the young Hercules, under promise of sharing the government: Polysperchon, however, unable to possess himself of the Peloponnesus which had been promised him, appears to have preserved but little influence. Cassander met likewise with formidable opponents in the persons of Antigonus and his son; and although delivered by the breaking out of the war with Ptolemy from the danger of the first invasion of Greece by Demetrius, his situation was more embarrassing at the second irruption; from which, however, he was extricated by the circumstance of Antigonus being obliged to recall his son, on account of the newly formed league (see above, p. 230).
