アッタロス朝
After the death of Philip's son Alexander the Great in 323 BC, the Thracian Chersonese became the object of contention among Alexander's successors. Lysimachus established his capital Lysimachia here. In 278 BC, Celtic tribes from Galatia in Asia Minor settled in the area. In 196 BC, the Seleucid king Antiochus III seized the peninsula. This alarmed the Greeks and prompted them to seek the aid of the Romans, who conquered the Thracian Chersonese, which they gave to their ally Eumenes II of Pergamon in 188 BC. At the extinction of the Attalid dynasty in 133 BC it passed again to the Romans, who from 129 BC administered it in the Roman province of Asia. It was subsequently made a state-owned territory ("ager publicus") and during the reign of the emperor Augustus it was imperial property.
