The Battle of Zlatica (1443) was fought on 12 December 1443 between the Ottoman Empire and Serbian Hungarian troops in the Balkans. The battle was fought at Zlatitsa pass (Turkish: Izladi Derbendi) in the Balkan Mountains, Ottoman Empire (modern-day Bulgaria). The impatience of the king of Poland and the severity of the winter then compelled Hunyadi (February 1444) to return home, but not before he had utterly broken the Sultan's power in Bosnia, Herzegovina, Serbia, Bulgaria, and Albania.
