Vuk Branković in the context of Gospodin

The Battle of Kosovo took place on 15 June 1389 between an army led by the Serbian Prince Lazar Hrebeljanović and an invading army of the Ottoman Empire under the command of Sultan Murad I. It was one of the largest battles of the Late Middle Ages.

The battle was fought on the Kosovo field in the territory ruled by Serbian nobleman Vuk Branković, in what is today Kosovo, about 5 kilometers (3.1 mi) northwest of the modern city of Pristina. The army under Prince Lazar consisted mostly of his own troops, a contingent led by Branković, and a contingent sent from Bosnia by King Tvrtko I, commanded by Vlatko Vuković. Additionally, Lazar was also supported by a Christian coalition from various European ethnic groups. Prince Lazar was the ruler of Moravian Serbia and the most powerful among the Serbian regional lords of the time, while Branković ruled the District of Branković and other areas, recognizing Lazar as his overlord.

The District of Branković (Serbian: Земља Бранковића / Zemlja Brankovića) or Vuk's Land (Serbian: Вукова земља / Vukova zemlja) was one of the medieval Serbian states that emerged from the collapse of the Serbian Empire in 1371. The founder of this realm was Vuk Branković, who would participate at the Battle of Kosovo in 1389. After the battle, Branković would become one of the most powerful Serbian regional rulers.

The District of Branković centred around present-day Kosovo, with cities such as Pristina being particularly important.

Miloš Obilić (Serbian Cyrillic: Милош Обилић, pronounced [mîloʃ ôbilit͡ɕ]) is a legendary Serbian knight and saint in the Serbian Orthodox Church traditionally said to have served Prince Lazar during the Ottoman invasion of Serbia in the late 14th century. Although absent from contemporary records, he features prominently in later accounts of the 1389 Battle of Kosovo as the assassin of Sultan Murad I. The assassin remains unnamed in historical sources until the late 15th century, but the widespread circulation of the story in Florentine, Serbian, Ottoman, and Greek sources suggests that versions of it were known across the Balkans within decades of the battle.

His original name is believed to have been Miloš Kobilić, though multiple variations exist in historical sources, and his actual existence remains uncertain. The Lazar dynasty, consolidating its power, gave birth to the Kosovo Myth, which incorporated the legend of Obilić. Jelka Ređep notes that Obilić's legend significantly evolved through oral tradition, reflecting Serbian cultural ideals of heroism, loyalty and sacrifice. Over time, he became a central figure in Serbian epic poetry, where he was elevated to the status of a national hero embodying medieval Serbian folklore. Alongside Prince Lazar’s martyrdom and the alleged treachery of Vuk Branković, Miloš's deed became integral to Serbian narratives surrounding the Battle of Kosovo. By the 19th century, he was also venerated as a saint in the Serbian Orthodox Church.
