The term Thraco-Roman describes the Romanized culture of Thracians under the rule of the Roman Empire.
The Odrysian kingdom of Thrace became a Roman client kingdom c. 20 BC, while the Greek city-states on the Black Sea coast came under Roman control, first as civitates foederatae ("allied" cities with internal autonomy). After the death of the Thracian king Rhoemetalces III in 46 AD and an unsuccessful anti-Roman revolt, the kingdom was annexed as the Roman province of Thracia.[1] The northern Thracians (Getae-Dacians) formed a unified kingdom of Dacia, before being conquered by the Romans in 106 and their land turned into the Roman province of Dacia.
