Summary: Vuk Branković was the youngest son of Emperor Dušan’s regent in Ohrid, Branko Mladenović. He closely cooperated with his father-in-law, Prince Lazar, recognizing his supremacy. He considerably expanded the territory under his rule, which was originally only in Drenica, by fighting against the families of Balšić and Dejanović, King Marko and Nikola Altomanović. The retreat of Bayezid’s army after the Battle of Kosovo, the demise of Prince Lazar and the weakness of his successors, led Vuk, who also took part in the Battle of Kosovo with his army, to act independently. In 1392 he started paying a toll to Bayezid I, but did not take part in his military operations. According to some unconfirmed sources, he was banished or imprisoned in 1395, and died two years later, some sources say, in prison. The regions under his rule were assigned by Bayezid to the family of Lazarević, and in 1402 to Vuk’s sons: Grgur, Djuradj and Lazar.
