Great Social War

The Great Social War, also known as the Great War of the Allies and the War of the Century, was a military conflict that raged from 40 to 48 AD, and part of a series of wars fought between the Antigonid and Seleucid Empires. The conflict was one of the largest in Antiquity and the largest during the Hellenistic Period, involving hundreds of thousands of troops from all sides combined.

The war was instigated when Antigonus XI Meton III sent dignitaries to the Galatian Celts to incite rebellions against Seleucid rule and promising self-determination, adding more manpower to his armies. Afterwards, an invasion of West Anatolia from the forces of the Antigonid-led Chalcidicean League commenced in an attempt to regain Pergamon and the rest of its former territories from the Seleucids. At Samosata, the Samosatian League was formed by Seleucus IX Anicetus to counter the invasions.
