Vlastimir of Serbia in the context of "Vlastimirović dynasty"

Travunia (Serbo-Croatian: Travunija / Травунија; Greek: Τερβουνία, romanized: Tervounía; Ancient Greek: Τερβουνία, romanized: Terbounía; Latin: Tribunia) was a South Slavic medieval principality that was part of Medieval Serbia (850–1371), and later the Medieval Bosnia (1373–1482). The principality became hereditary in a number of noble houses, often kin to the ruling dynasty. The region came under Ottoman rule in 1482. Its seat was in the city of Trebinje.

In the 9th and 10th centuries, the Župa of Travunia was held by the Belojević noble family, who were entitled the rule during the reign of Prince Vlastimir (r. 830–850), of the Vlastimirović dynasty. After the death of Časlav, the last dynastic member, the principality disintegrated, and the provinces were annexed by the Bulgars and Byzantines. In 1034, Stefan Vojislav (the founder of the Vojislavljević dynasty) incited a rebellion and renounced Byzantine rule, becoming the Prince of Serbs, ruling from the seat at Duklja. In the early 12th century, Desa of the Vukanović dynasty wrestled the region, and it continued under the rule of the Nemanjić dynasty (1166–1371), either held by dynastic members or close associates (most often military commanders), of which was the notable Vojinović noble family. After Nikola Altomanović, the holder of a large province during the fall of the Serbian Empire, was defeated in 1373, his estates were divided between Prince Lazar Hrebeljanović of Serbia, Đurađ I Balšić of Zeta, and Ban Tvrtko I Kotromanić of Bosnia. Trebinje continued under the Bosnian crown in the hands of the Pavlović family, and from 1435 under the Kosača family. It was finally annexed in 1481 by the Ottomans and organized into the Sanjak of Herzegovina.

Krajina Belojević (Serbian: Крајина, Greek: Κράινα), 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 (Greek: Φαλιμἑρης). Hvalimir in turn had a son, Čučimir (Greek: Τζουτζημέρης; r. first half of 10th century), who was the last known Belojević in charge of Travunia before it was annexed by the Byzantines.
