Wars of the Diadochi

The Battle of Salamis, fought off Cyprus in 306 BC, was a naval engagement between the fleets of Ptolemy I of Egypt and Antigonus I Monophthalmus during the Wars of the Diadochi — the prolonged contest among Alexander the Great's successors for control of his empire. The confrontation placed Antigonid forces under Demetrios against Ptolemaic forces under Ptolemaios and Menelaos, reflecting the broader rivalry between two of the most powerful successor dynasties. Cyprus, as a strategically positioned island in the eastern Mediterranean, represented a significant prize in this contest, and the engagement off its coast formed part of the wider struggle to dominate the sea lanes and territories that had once constituted Alexander's unified empire.

The Battle of Corupedium, fought in 281 BC, was the last engagement between the Diadochi — the rival successors of Alexander the Great — and brought the Wars of the Diadochi to a close. Lysimachus, who had ruled Thrace for decades, controlled parts of western Asia Minor since the Battle of Ipsus, and had more recently consolidated power over Macedon, was killed during the fighting, reportedly by a javelin thrown by Malacon, a Heracleian soldier serving under Seleucus. His death ended the Lysimachid Kingdom as a contending power. Seleucus I Nicator, already ruler of an empire stretching across lands corresponding to modern eastern Turkey, Syria, Lebanon, Israel, Iraq, and Iran, emerged as the last surviving major successor, briefly leaving him without a peer among Alexander's former generals. The battle thus marked the end of the generation-long contest over Alexander's inheritance, consolidating the post-Alexandrian world under Seleucid dominance — at least momentarily, before further fragmentation set in.
