 The Romans colonized the province extensively, beginning a period of intense romanization, during which the language Vulgar Latin morphed into the Proto-Romanian language.Dacia's geographical position made it difficult to defend against the barbarians and during 240–256 AD, Dacia was lost under attacks of the Carpi and the Goths.The Roman Empire withdrew from "Dacia Romana" around 271 AD, making it the first province to be abandoned.
