The Battle of Corupedium (also called Corupedion), the name of the last battle of the Diadochi, the rival successors to Alexander the Great, is fought between the armies of Lysimachus and Seleucus I. Lysimachus has ruled Thrace for decades and parts of Western Turkey ever since the battle of Ipsus.

Recently he had finally gained control over Macedon.

Seleucus rules Eastern Turkey, Syria, Lebanon, Israel, Iraq and Iran.

Almost nothing is known about the battle itself save that the two aged kings meet in hand to hand combat and Seleucus wins the battle.

Lysimachus dies during the fighting.

According to Memnon's History of Heracleia, Lysimachus is killed by a javelin thrown by Malacon, a Heracleian soldier serving under Seleucus.
