By 1271, Dragutin received the title of "young king" in recognition of his right to succeed his father. He rebelled against his father, and with Hungarian assistance, forced him to abdicate in 1276. Dragutin abandoned Uroš I's centralizing policy and ceded large territories to his mother in appanage. After a riding accident, he abdicated in favor of his brother, Milutin, in 1282, but he retained the northern regions of Serbia along the Hungarian border. Two years later, his brother-in-law, Ladislaus IV of Hungary, granted him three banates—Mačva (or "Sirmia ulterior"), Usora and Soli. 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.
