Dragutin administered his realm independently of his brother. He supported the Franciscans' missions in Bosnia and allowed the establishment of a Catholic see in Belgrade. Two Cuman or Bulgarian warlords, Darman and Kudelin, had seized a former Hungarian banate, the Banate of Braničevo. Dragutin invaded Braničevo with Hungarian assistance in 1284 or 1285 but could not defeat them. Darman and Kudelin hired Cuman and Tatar troops and began raiding Dragutin's realm. Dragutin sought help from Milutin and the two brothers met in Mačkovac. After they joined their forces and defeated Darman and Kudelin, Dragutin seized Braničevo in 1291 or 1292. The new Hungarian monarch, Andrew III, also supported their military action, but Andrew's weak position in Hungary enabled Dragutin to strengthen his independence.
