Kingdom of Serbia (1217–1346) in the context of "Sandžak"

The Grand Principality of Serbia (Serbian: Великожупанска Србија / Velikožupanska Srbija), also known by the anachronistic exonym Rascia (Serbian: Рашка / Raška), was a medieval Serbian state that existed from the second half of the 11th century up until 1217, when it was transformed into the Kingdom of Serbia. After the Grand Principality of Serbia emerged, it gradually expanded during the 12th century, encompassing various neighbouring regions, including territories of Raška (Serbian Cyrillic: Рашка; Latin: Rascia), modern Montenegro, Herzegovina, and southern Dalmatia. It was founded by Grand Prince Vukan, who initially served as the regional governor of the principality (c. 1082), appointed by King Constantine Bodin. During the Byzantine–Serbian wars (c. 1090), Vukan gained prominence and became a self-governing ruler in the inner Serbian regions. He founded the Vukanović dynasty, which ruled the grand principality. Through diplomatic ties with the Kingdom of Hungary, Vukan's successors managed to retain their self-governance, while also recognizing the supreme overlordship of the Byzantine Empire, up to 1180. Grand Prince Stefan Nemanja (r. 1166–1196) gained full independence and united almost all Serbian lands. His son, Grand Prince Stefan was crowned King of Serbia in 1217, while his younger son Saint Sava became the first Archbishop of Serbs, in 1219.

Serbs of Bosnia and Herzegovina or Bosnian Serbs, are one of the three constituent peoples of Bosnia and Herzegovina. According to data from the 2013 census, the population of ethnic Serbs in Bosnia and Herzegovina was 1,086,733, constituting 30.8% of the total population; they are the second-largest ethnic group in the country (after Bosniaks) and live predominantly in the political-territorial entity of Republika Srpska.

Serbs have a long history of inhabiting the present-day territory of Bosnia and Herzegovina as well as long history of statehood in that territory. Slavs settled the Balkans in the 6th century and the Serbs were one of the main tribes who settled the peninsula including parts of modern-day Bosnia and Herzegovina. Parts of Bosnia were ruled by the Serbian prince Časlav in the 10th century while the southeastern and eastern parts became integrated into the Serbian medieval state under the Nemanjić dynasty by the 13th-14th centuries. After the Ottoman conquest of Bosnia and Herzegovina, the majority of the Orthodox Christian population in the region retained their Serbian ethnic and religious identity under the restored Serbian Patriarchate of Peć, while many landowners converted to Islam. Throughout the period of Ottoman rule, the Serbs of Bosnia and Herzegovina, formed the core of several major uprisings against Ottoman rule. In 1878, following the Congress of Berlin, Austria-Hungary occupied Bosnia and Herzegovina, facing resistance from the Serb population, which increasingly aspired to unification with the Kingdom of Serbia, culminating in growing tensions that contributed to the assassination of Archduke Franz Ferdinand in Sarajevo, which triggered the World War I.

The Visoki Dečani Monastery is a medieval Serbian Orthodox Christian monastery located near Deçan, Kosovo. It was founded in the first half of the 14th century by Stefan Dečanski, King of Serbia.

Dečani is by far the largest medieval church in the Balkans. Its architectural style, which emerged in Kingdom of Serbia at the end of the 12th century, combines Orthodox traditions with Romanesque influences and is regarded as one of the most complex architectural achievements of the 14th century. The monastery reflects the cultural exchange between the East and West, representing Serbia's historical position during the medieval period. The Dečani church contains frescos that show defining moments from both Serbian history and Christian tradition. It also features the largest preserved collection of Byzantine painting. For centuries, Dečani has played a key role in preserving the spiritual, cultural, and national identity of Serbs in Kosovo.
