Another campaign, this time organized by both Dragutin and Elizabeth, failed to conquer Darman and Kudelin's domains in 1285 and suffered another counter-raid by the brothers. It was not until 1291 when a joint force of Dragutin and the Serbian King Stefan Milutin managed to defeat the brothers and, for the first time ever, the region came under the rule of a Serb, as it was annexed by Dragutin. Responding to Dragutin's annexation of Braničevo the Bulgarian prince named Shishman that came to rule the semi-independent principality of Vidin around 1280, began to attack the Serbian domains to his west.
