Almost at the same time, Antipater died, leaving his son, Cas-san´der, and his general, Pol-ys-per´chon, to quarrel over the government of Macedon. Each gathered together an army, and tried to get as many friends as possible, especially among the Greeks.
The Athenians vainly tried to remain neutral during this quarrel; but in the course of the war, Polysperchon came into their city, said that Phocion and many other great citizens were siding with Cassander, and condemned them to die by drinking poison brewed from the hemlock plant.
It seems, however, that there was not enough poison ready to kill them all, so the jailer made Phocion give him some money to buy more. The noble old man, forced to do as he was bidden, gave the necessary amount, saying, "It seems that one cannot even die for nothing in Athens."
As he was the last really noted politician in the city, he has been called the "Last of the Athenians." No one ever dared to uphold the city's power after his death, or tried to help it win back its old freedom.
As soon as Perdiccas was dead, Roxana and her son were brought to Macedon, where they were finally placed under the protection of Polysperchon. When Olympias, the mother of Alexander the Great, saw his infant son, she was so anxious to secure the throne for him alone, that she slew the idiot king Arridæus and all his family.
Under pretext of avenging this crime, Cassander captured and slew Olympias; and then, having won Macedon and Greece from Polysperchon, and seeing that there was no one left to protect Roxana and the child king, he put both mother and son in prison, where they were killed by his order shortly after.
Thus, twelve years after Alexander's death, all his family were dead, and his vast kingdom was a prey to quarreling, which broke it up into several states.
