282 BCE
The city of Pergamum in Asia Minor ends its allegiance to Lysimachus. Its ruler, Philetaerus, transfers his allegiance, as well as the important fortress of Pergamon and his treasury, to Seleucus, who allows him a far larger measure of independence than he had hitherto enjoyed. The Battle of Populonia is fought between Rome and the Etruscans. The Romans are victorious and, as a result, the Etruscan threat to Rome is sharply diminished. Arsinoe, daughter of Lysimachus, king of Thrace, marries Ptolemy II of Egypt as part of the alliance between Thrace and Egypt against Seleucus.
