Cause → Event → Consequence
Cyprus had been seized by Ptolemy and used as a base for operations against Antigonid territories in Asia Minor and the Levant. In 306 BC, Antigonus dispatched his son Demetrius to retake the island, which was defended by Ptolemy's brother Menelaus. Demetrius landed on the northeastern coast, defeated Menelaus in a land engagement, and besieged the city of Salamis.
Ptolemy personally led a large relief fleet to rescue Menelaus and break the siege. Demetrius took a calculated risk, leaving a small force to contain Menelaus while concentrating his main fleet against Ptolemy. The resulting naval battle was a decisive Antigonid victory: Demetrius destroyed or captured much of Ptolemy's fleet and army, after which Menelaus and his garrison surrendered.
Following the battle, Demetrius completed the conquest of Cyprus. Buoyed by the victory, Antigonus assumed the royal title left vacant since Alexander's line ended, and the other Diadochi—Ptolemy, Seleucus, Lysimachus, and Cassander—soon followed suit, formally inaugurating the Hellenistic kingdoms and reshaping the political order of the eastern Mediterranean.
