In theory, Dragutin was a vassal both to his brother (for his Serbian territories), and to the Hungarian monarchs (for the four banates), but in practice he ruled his realm as an independent ruler from the 1290s. His conflicts with Milutin developed into open war in 1301, and he frequently raided the neighboring Hungarian lords from 1307. Most of the Serbian noblemen supported Dragutin, but he was forced to make peace with Milutin after Milutin's mercenaries routed him in 1311 or 1312. Before his death, he entered a monastery and died as the monk Teoktist. On the list of Serbian saints, Dragutin is venerated on 12 November or 30 October (Old Style and New Style dates).
