Antigonus I, also known as Monopthalmos, or Cyclops for having lost an eye, was the founder
of the Antigonid Dynasty and one of the most important figures during the wars of the Diodochi,
following the death of Alexander the Great. He was made governor of Phrygia shortly
after Alexander the Great conquered Asia Minor. He held the position for ten years, and
at the time of Alexander's death, several other provinces in Asia Minor were added to his command.
He soon however, incurred the wrath of Perdiccas, who was Alexander's nominal successor,
and fled to Greece with his son Demetrius, to the protection of Antipater, the regent
|BATTLE OF ISSUS|
Two years after the original partition of Alexander's empire, Perdiccas was assassinated,
and Antigonus led and army into Asia Minor to contend with Eumenes, who was allied with
Perdiccas and had inherited his realms. Eumenes was completely
defeated, and obliged to retire to Cappadocia. This state of affairs lasted for
about three years, until Antipater
died, at which point a war for the succession of Macedonia broke out. In this second War
of the Diodochi, Antiochus was allied with Cassander, the son of Antipater, while his
enemy Eumenes was allied with Polyperchon, Cassander's rival. After numerous furious
battles between Antigonus and Eumenes in Asia, Eumenes was captured and delivered into
the hands of Antigonus through treachery, after which he was put to death. Antigonus
then claimed authority over the whole of Asia, seized the treasures at Susa, and drove
Seleucus out of Babylonia.
Antiochus had gained such great power in Syria and Asia that he threatened the other Diodochi,
and they formed
an alliance against him. These included Ptolemy (Egypt), Lysimachus (Thrace),
Cassander (Macedonia), and Seleucus (Babylon). After the war had been carried on with varying success from
315 to 311 B.C., peace was concluded, by which the government of Asia Minor and Syria was provisionally
secured to Antigonus. This agreement was soon violated on the pretext that garrisons had been placed
in some of the free Greek cities by Antigonus, and Ptolemy and Cassander renewed hostilities against
him. Demetrius Poliorcetes, the son of Antigonus, wrested part of Greece from Cassander. At first
Ptolemy had made a successful descent upon Asia Minor and on several of the islands of the
Archipelago; but he was at length totally defeated by Demetrius in a naval engagement off Salamis,
in Cyprus (306 B.C.). On this victory Antigonus assumed the title of king, and bestowed the same upon his
son, a declaration that he claimed to be the heir of Alexander. Antigonus now prepared a large army,
and a formidable fleet, the command of which he gave to Demetrius, and hastened to attack Ptolemy in
his own dominions. His invasion of Egypt, however, proved a failure; he was unable to penetrate the
defences of Ptolemy, and was obliged to retire. Demetrius now attempted the reduction of Rhodes,
which had refused to assist Antigonus against Egypt; but, meeting with obstinate resistance, he was
obliged to make a treaty upon the best terms that he could (304). In 302 B.C., although Demetrius was
again winning success after success in Greece, Antigonus was obliged to recall him to meet the
confederacy that had been formed between Cassander, Seleucus and Lysimachus. A decisive battle was
fought at Ipsus, in which Antigonus fell, in the eighty-first year of his age.
