Dacia

Dacia (/ˈdeɪʃə/, DAY-shə; Latin: [ˈd̪aː.ki.a]) was the land inhabited by the Dacians, its core in Transylvania, stretching to the Danube in the south, the Black Sea in the east, and the Tisza in the west. The Carpathian Mountains were located in the middle of Dacia. It thus roughly corresponds to the present-day countries of Romania, as well as parts of Moldova, Bulgaria, Serbia, Hungary, Slovakia, and Ukraine.

A Dacian kingdom that united the Dacians and the Getae people existed between 82 BC until the Roman conquest in AD 106, reaching its height under King Burebista. As a result of the two wars with Emperor Trajan, the population was dispersed and the central city, Sarmizegetusa Regia, was destroyed by the Romans, but was rebuilt by them 40 km away to serve as the capital of the Roman province of Dacia. A group of "Free Dacians", may have remained outside the Roman Empire in the territory of modern-day Northern Romania until the start of the Migration Period. The provincial area was conquered by the Romans and incorporated as Roman Dacia, and the area was controlled by the Romans from the conquest in AD 106 to AD 275, over a century of rule.
