A Turkish raiding party, passing unobstructed through territories of Ottoman vassals, broke into Moravian Serbia in 1381. It was routed by Lazar's nobles Crep Vukoslavić and Vitomir in the Battle of Dubravica, fought near the town of Paraćin. In 1386, the Ottoman Sultan Murad I himself led much larger forces that took Niš from Lazar. It is unclear whether the encounter between the armies of Lazar and Murad at Pločnik, a site southwest of Niš, happened shortly before or after the capture of Niš. Lazar rebuffed Murad at Pločnik.
