Featuring items of the Bijelo Brdo culture (the dominant archaeological culture of the Carpathian Basin between around 950 and 1090) can be detected in the lowlands from around 975. Artefacts from the Byzantine Empire or imitating Byzantine objects were found along the Danube, and in the Banat Mountains. Pagan burial rites disappeared by the end of the 11th century, evidencing the local inhabitants' conversion to Christianity.

More than a dozen monasteries (including at least three Orthodox monasteries) were established in the region before the mid-13th-century.
