Abdera was a town on the coast of Thrace near the mouth of the Néstos River. It was named after Abderus, son of Hermes. The people of Teos, evacuating Ionia when it was overrun by the Persians under Cyrus (c.540 BCE), succeeded in establishing a colony. It developed a brisk trade with the Thracian interior. Abdera was a prosperous member of the Delian League in the 5th century but was crippled early in the 4th century BCE by Thracian incursions and declined sharply in importance. The philosophers Protagoras and Democritus were citizens of Abdera. The site is occupied by the modern town of Ávdhira, Greece.
