Marchland

Extracted from the Wikipedia article March (territory).
Hungary
Portions of the gyepű were usually guarded by tribes who had joined the Hungarian nation and were granted special rights for their services at the borders, such as the Székelys, Pechenegs and Cumans. A ban on settlement north of Niš by the Byzantine Empire in the twelfth century helped to establish uninhabited marchland between the empire's territory and Hungary.
