Roman Dacia

Roman Dacia (also Dacia Traiana and Dacia Felix) was a province of the Roman Empire from 106 to 274–275 AD. Its territory consisted of eastern and south-eastern Transylvania, the Banat, and Oltenia (regions of modern Romania). It was from the very beginning organized as an imperial province and remained so throughout the Roman occupation. Historians' estimates of the population of Roman Dacia range from 650,000 to 1,200,000.
