Battle of Kosovo

The Battle of Kosovo, also known as the Battle of Kosovo Field or the Battle of Blackbird's Field (Serbian: Косовска битка, Бој на Косову; Kosovska bitka; Boj na Kosovu; Turkish: Kosova Meydan Savaşı), took place on St. Vitus' Day, June 15, 1389, between the army led by Serbian Prince Lazar Hrebeljanović, and the invading army of the Ottoman Empire under the leadership of Sultan Murad I. The army under Prince Lazar consisted of his own troops, a contingent led by Serbian nobleman Vuk Branković, and a contingent sent from Bosnia by King Tvrtko I, commanded by Vlatko Vuković.^[7][9] Prince Lazar was the ruler of Moravian Serbia, and the most powerful among the Serbian regional lords of the time, while Vuk Branković ruled a part of Kosovo and other areas, recognizing Lazar as his overlord. The Battle of Kosovo took place in the Kosovo Polje, about 5 kilometers northwest of modern-day Pristina.
