Darman (Bulgarian: Дърман; also Drman, Dǎrman, Durman, Dorman) and Kudelin (Куделин) were two Bulgarian nobles who jointly ruled the region of Braničevo (in modern Serbia) as independent or semi-independent autocrats in the late 13th century (1273–1291). Regarded by historians to be "probably Bulgarians of Cuman origin", the two brothers used the weakened state of centralized administration in the region to become independent from the Second Bulgarian Empire or the Kingdom of Hungary in 1273. The capital of their domains was the fortress of Zhdrelo (Ždrelo, "gorge"), on the Mlava river. Relying on their army that consisted of people of various ethnicities, but mostly Vlachs, Bulgarians, Tatars and Cumans, the brothers were "very independent-minded and afraid of no one".
