Dacia was a region inhabited by the Dacians in the north of the Danube (modern Romania). The kingdom of Dacia was the creation of Burebistas (c. 80-44 BCE), who conquered and united several other Dacian principalities. Burebistas practically destroyed the Celtic tribes of the Scordiscii and subjected, or allied with, the Greek cities of the Western Black Sea coast, from Odessus (today's Varna) to Olbia (near today's Odessa). During the Roman Civil War, the Dacians would probably have come to support Pompey. Burebistas was eventually killed in the same year as Julius Caesar, who allegedly was preparing an expedition against the Dacians and the Parthians.
