Historical names of Transylvania are:
In Romanian, the region is known as Ardeal (pronounced ) or Transilvania (pronounced ); in Hungarian as Erdély (pronounced ); in German as Siebenbürgen (pronounced ( listen)); and in Turkish as Transilvanya (pronounced ) but historically as Erdel or Erdelistan; see also other denominations.
Transylvania has been dominated by several different peoples and countries throughout its history. It was once the nucleus of the Kingdom of Dacia (82 BC–106 AD). In 106 AD the Roman Empire conquered the territory, systematically exploiting its resources. After the Roman legions withdrew in 271 AD, it was overrun by a succession of various tribes, bringing it under the control of the Carpi, Visigoths, Huns, Gepids, Avars and Slavs. From 9th to 11th century Bulgarians ruled Transylvania. It is a subject of dispute whether elements of the mixed Daco–Roman population survived in Transylvania through the Dark Ages (becoming the ancestors of modern Romanians) or the first Vlachs/Romanians appeared in the area in the 13th century after a northward migration from the Balkan Peninsula. There is an ongoing scholarly debate over the ethnicity of Transylvania's population before the Hungarian conquest (see Origin of the Romanians).
