- The city of Pergamum is attacked by the Galatians (Celts who have settled in central Anatolia) because the leader of Pergamum, Attalus I Soter, has refused to pay them the customary tribute. Attalus defeats his enemy in a battle outside the walls of his city. To mark the success he takes the title of king and the name Soter.
- King Agron of Illyria dies. Pinnes, the son of Agron and Agron's first wife Triteuta, succeeds his father as king. The kingdom is really ruled by Agron's second wife, Queen Teuta (Tefta).

She keeps her husband's way of attacking cities on the west coast of Greece.
