The Serbian Empire came under Turkish domination after which battle in 1389?
Serbian-Turkish Wars (1876-1878) breechloaders are most frequently mentioned although there must have been significant numbers of bronze guns. Ottoman troops performed well during the war albeit badly officered and inadequately supplied. The first phase, known as the First Serbian–Ottoman War (Први српско-турски рат / Prvi srpsko-turski rat), took place between 30 June 1876 and 28 February 1877.

The initial Serbian military plan was to defend Niš and attack Sofia with the main army under Chernyayev. Other armies would simultaneously launch
Serbian Empire conquered first Byzantine Thrace, and then the other Balkan states. Too incompetent to sustain the empire created by his father, Stefan V could neither repel attacks of foreign enemies nor combat the independence of his nobility. The Serbian Empire of Stefan V fragmented into a conglomeration of principalities, some of which did not even nominally acknowledge his rule. Stefan Uroš V died childless on 4 December 1371, after much of the Serbian nobility had been killed by the Ottoman Turks during the Battle of Maritsa. The crumbling Serbian Empire under Uroš the Weak offered little resistance to the powerful Ottomans.
