He was the first Serbian monarch to rule Belgrade.
With his brother's support, he also occupied the Banate of Braničevo in 1284 or 1285.
Dragutin was in theory a vassal both to his brother (for his Serbian territories), and to the Hungarian monarchs (for the four banates), but he actually ruled his realm as an independent ruler from the 1290s.
His conflicts with Milutin developed into an open war in 1301 and he made frequent raids against 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 into a monastery and died as the monk Teokist.
In the list of Serbian saints, Dragutin is venerated on 12 November or 30 October (Old Style and New Style dates).
