THE FALL OF ANTIGONUS
[301-300 B.C.]
Seleucus who was now master of Babylon and the upper satrapies, after having subdued all Iran as far as India without any effort, had formed, together with Ptolemy, Cassander, and Lysimachus, a coalition against Antigonus. This is the first instance known in history, of a great coalition of princes of equal rank and equal independence. Antigonus, who now possessed only Asia Minor, Cyprus, a portion of Syria and the greater part of Greece, was thus opposed by all the rest of the Macedonian world; and it was against this coalition that Demetrius led his army into Asia Minor. We know very little about the details of the war, but it appears that the enemies pressed into Asia Minor from all sides. The decisive battle was fought near Ipsus in Phrygia; it was decided especially by the admirable infantry of Lysimachus and Cassander. Seleucus had only Asiatics; the phalanx of Ptolemy was of little importance, and only his mercenaries fought bravely; but the truth is that in reality he had no talent as a commander. Antigonus fell in the battle, and the defeat was so complete, that his whole empire was destroyed. Demetrius escaped with a small band to the maritime towns of Ionia, but behaved in a praiseworthy manner.
The empire of Antigonus was now cut up: the western provinces were divided between Cassander and Lysimachus, the upper provinces were assigned to Seleucus, and Cyprus and Syria to Ptolemy, who, however, did not maintain upper Syria, but confined himself to Phœnicia and Cyprus. Plistarchus, a brother of Cassander obtained Cilicia as a special indemnification for Cassander, who himself received Caria and Pamphylia, while Lysimachus acquired Lydia, Ionia, Phrygia, and the north coast of Asia Minor.
