What happened
On 15 June 1389, an Ottoman army under Sultan Murad I met a Christian coalition led by Serbian Prince Lazar Hrebeljanovic, joined by troops from Bosnia under Vlatko Vukovic, on the plain of Kosovo Polje. Murad split his forces into three, commanding the center himself while his sons Bayezid and Yakub led the wings. Both Murad and Lazar died in the fighting; later tradition holds that a Serbian knight, Miloš Obilic, killed Murad by feigning surrender and then stabbing him, though historians treat this story as legend rather than established fact. Murad's son Bayezid secured the succession on the battlefield itself, reportedly by having his brother Yakub strangled to remove a rival claimant, and returned to Edirne as the new sultan.
Why it matters
The battle broke the last major coordinated Serbian resistance in the Balkans and left the Ottomans in control of the field even though losses on both sides were heavy enough that neither claimed a clean tactical victory. Serbia became an Ottoman vassal state in the years that followed, and Kosovo became the central historical memory of Serbian national identity for centuries afterward.
How we know
Thomas Emmert's essay for the University of Arizona's Center for Middle Eastern Studies works from the earliest surviving reports of the battle, including a 1 August 1389 letter from Tvrtko I of Bosnia to the Dalmatian city of Trogir announcing a victory, and notes how quickly and how differently the battle was reported even in its own summer.
