In page Braničevo District:

"

By the 12th century, Braničevo was the centre of a Byzantine doukaton (duchy) governed by a doux (duke). The region saw significant fighting between the Byzantines and Hungarians. With the rise of the Second Bulgarian Empire and the Kingdom of Serbia, Byzantium's position in Braničevo became untenable. It appears to have finally slipped from their control in 1198. It was a frequent object of contention between the Bulgars, Serbs and Hungarians thereafter.[2]
