After the battle, in 1390 or 1391 depending on source, Serbia became a vassal Ottoman state, and Stefan Lazarević was obliged to participate in battles if ordered by the Ottoman sultan. He did so in the Battle of Rovine in May 1395 against the Wallachian prince Mircea I and the Battle of Nicopolis in 1396 against the Hungarian king Sigismund. After that, Sultan Bayezid awarded Stefan with the majority of the Vuk Branković's land on Kosovo, as Branković sided with the Hungarian king at Nicopolis.
