Inscriptions on frescos and diplomatic correspondence provide evidence that Dragutin was styled "king" after his abdication, but Milutin's supreme position is evident. Dragutin continued to style himself as king in his charters and on his coins. Dragutin and Milutin wore royal insignias seen on a fresco in St. Achillius Church, which was Dragutin's endowment near Arilje, but Dragutin is depicted with fewer royal emblems. Actually, Serbia was divided between Dragutin and Milutin at Dragutin's abdication, with Dragutin retaining the northern region along the Hungarian border, including the recently opened silver mine at Rudnik. He also held territories in western Serbia on the river Lim, thus he was his brother's most powerful vassal. Ladislaus IV of Hungary granted Mačva, Usora and Soli to Dragutin in the second half of 1284. Relatives of the Hungarian monarchs, most recently by Dragutin's mother-in-law, Elizabeth the Cuman, had held the same territories in appanage, and Dragutin continued to rule them as a Hungarian vassal. Mačva was also known as "Sirmia ulterior", hence Dragutin's contemporaries often styled him as "King of Srem". He took up his seat at Debrc on the Sava, but he also regularly stayed in Belgrade, thus he was the first Serbian monarch to rule this town.
