Lysimachus

Lysimachus declared himself king of Thrace, establishing a Hellenistic kingdom in the region. He ruled over Thrace, parts of Asia Minor, and later Macedonia, but his kingdom was short-lived and fragmented after his death.

Lysimachus fought alongside Seleucus I against Antigonus I at Ipsus. The victory allowed Lysimachus to expand his territory in Asia Minor, gaining control of much of Anatolia. However, his alliance with Seleucus later turned to conflict.

Lysimachus ordered the execution of his son Agathocles on the instigation of his wife Arsinoe II. This act caused a revolt among his subjects and led to the defection of many supporters to Seleucus, weakening Lysimachus' position before Corupedium.

Lysimachus fought against Seleucus I at Corupedium in Lydia. He was defeated and killed in battle, ending his rule. This victory allowed Seleucus to claim control over Asia Minor, but Seleucus was assassinated shortly after.
