Krajina Belojević, was the 9th century local Slavic chieftain from the region surrounding Trebinje, who ruled the area with a title of župan., The same region centered on Trebinje, also known as Travunia, was earlier ruled by Krajina's father, the local lord Beloje. At the time of Krajina's rule, the region was still under suzerainty of the Principality of Serbia, and he was in vassal relation to its ruling Vlastimirović's. In 847/848, after the Bulgarian–Serbian War (839–842), victorious Prince Vlastimir of Serbia (r. ca. 836-850) married his unnamed daughter to Krajina, thus elevating his and his province rank. In doing so his father-in-law, eponymous founder of the Vlastimirović's, dynasty which rule Serbia until 969, granted them independence. Although Krajina's father sought to free himself and his province from Serbian suzerainty, and though Krajina succeeded in achieving that goal through marriage with Vlastimir's daughter, he continued to serve in office as župan under Mutimir (r. 850–891). With the Vlastimir's daughter Krajina had a son that would succeed him, Hvalimir. Hvalimir in turn had a son, Čučimir (r. first half of 10th century ), who was the last known Belojević in charge of Travunia before it was annexed by the Byzantines.
