The Battle of Tripolje took place in November 1402 between the Serbian Despotate and the Brankovic family. The Brankovic family, who were attempting to seize the Serbian throne for themselves, entered the battle along with Ottoman troops given to them by Suleiman, and were decisively defeated by Stefan Lazarević. The Serbian Lazarevic army had come from Zeta (in modern-day Montenegro). A local Serb lord, Đurađ II of the Balšić dynasty, the Despot's brother-in-law, had prepared the Despot for establishment of his rule on the field of battle as well.
