Vlastimirović dynasty in the context of "Principality of Serbia (early medieval)"

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.

The Belojević clan (Serbian Cyrillic: Белојевић), colloquially Travunian dynasty, was a local Slavic ruling clan from region surrounding Trebinje, a center of an early Slavic polity, Travunia. The clan was in vassal relations with the first Serbian Principality's ruling Vlastimirović's, but constantly strived for independence starting with the clan's progenitor Beloje, who sought to free himself of Serbian rule. Beloje was mentioned as the župan of Travunia in the chapter on the Serbs in De Administrando Imperio (DAI) of Byzantine Emperor Constantine VII (r. 945–959). Prince Vlastimir (r. 836–851) married his daughter to Beloje's son Krajina, and elevated him to the rank of archon, sometime prior the Bulgar–Serb War (839–842). Krajina's descendants were entitled to rule the region comprising the hinterland of Dubrovnik and Boka Kotorska, with seat at Trebinje, still under Serbian suzerainty. The clan is later mentioned in the semi-mythical Chronicle of the Priest of Duklja, which mentioned that a descendant of Hvalimir, Dragomir, ruled Travunia in the second half of the 10th century, his brother Petrislav ruling Duklja and his son Stefan Vojislav later ruling Duklja and founding the Vojislavljević dynasty.

Vlastimir (Serbian Cyrillic: Властимир, Greek: Βλαστίμηρος; c. 805 – 851) was the prince of Serbia from c. 830 until c. 851. Little is known of his reign. He held Serbia during the growing threat posed by the neighbouring, hitherto peaceful, First Bulgarian Empire, which had expanded significantly toward Serbia.

At the time, the Bulgarian Empire and the Byzantine Empire were at peace by treaty, and although the Byzantine Emperor was overlord of the Serb lands, he was unable to aid the Serbs in a potential war. Presian I of Bulgaria eventually invaded Serbia, resulting in a three-year-war, in which the Bulgarian army was devastated and driven out. Vlastimir then turned to the west, expanding well into the hinterland of Dalmatia. He is the eponymous founder of the Vlastimirović dynasty, the first Serbian dynasty.

Tzeésthlabos (Greek: Τζεέσθλαβος), usually transliterated as Časlav (Serbian Cyrillic: Часлав) or Chaslav and Tzeeslav, was Prince of the Serbs from c. 933 until his death in c. 943/960.

Časlav was the son of Klonimir, a son of Strojimir who ruled as co-prince in 851–880. He belongs to the first Serbian dynasty, the Vlastimirovićs (ruling since the early 7th century), and is the last known ruler of the family. His mother was a Bulgarian noblewoman chosen as wife of Klonimir by Boris I of Bulgaria himself.

Višeslav (Serbian Cyrillic: Вишеслав) or Vojislav (Serbian Cyrillic: Војислав), from Boïsesthlabos (Greek: Βοϊσέσθλαβος), was a Serbian ruler and the first known by name, who ruled in c. 780. Serbia was a Slavic principality, subject to the Byzantine Empire, located in the western Balkans, bordering with Bulgaria in the east. Mentioned in the De Administrando Imperio (DAI) from the mid-10th century, Višeslav was a progenitor of the Serbian ruling family, known in historiography as the Vlastimirović dynasty. He was descended from the unnamed Serbian prince who led his people to the Dalmatia province and established hereditary rule under Byzantine suzerainty. The names of Višeslav's predecessors were not included in the DAI. The dynasty ruled the Principality of Serbia from the early 8th century until around 960.

The history of Serbia covers the historical development of Serbia and of its predecessor states, from the Early Stone Age to the present state, as well as that of the Serbian people and of the areas they ruled historically. Serbian habitation and rule has varied much through the ages, and as a result the history of Serbia is similarly elastic in what it includes.

After early Slavs first appeared in the Balkans in the 6th and 7th centuries, they mixed with local Byzantine subjects, descendants of Paleo-Balkan tribes, such as the Thracian, Dacian, Roman, Illyrian and former Roman colonists. The First Serbian Principality was established in the 8th century by the Vlastimirovići dynasty ruling over modern-day Montenegro, Bosnia, Dalmatia, and Serbia. It evolved into a Grand Principality by the 11th century, and in 1217 the Kingdom and national church (Serbian Orthodox Church) were established, under the Nemanjić dynasty. In 1345 the Serbian Empire was established, spanning most of the Balkan peninsula. In 1540 Serbia became a part of the Ottoman Empire.
