The Greeks founded several colonies on the Thracian coasts, the most notable being Byzantium. On the Black Sea's Gulf, the Milesians founded Apollonia in the 7th century BC, and the Chalcedonians founded Mesembria in the 6th century BC. Most Thracians became subjects to Persia by 516 BC . The Thracians were assimilated into Macedon by Philip II and united by his son Alexander the Great. In 197 BC, it was made a part of Pergamum by the Romans. Emperor Claudius I annexed all of Thrace in 46 AD and it was made into a Roman province. In the Byzantine empire it was a mint and a military center. It was officially established in the early 830s and was an important centre of Black Sea commerce. Despite the destruction of the city of Cherson in the 980s, the theme recovered and prospered, enduring until it became a part of the Empire of Trebizond after the dissolution of the Byzantine Empire in 1204.
