on Kosovo field In 1389, Murad's army fought the Serbian Army and its allies under the leadership of Lazar at the
Battle of Kosovo. There are different accounts from different sources about when and how Murad I was assassinated. The contemporary sources mainly noted that the battle took place and that both Prince Lazar and the Sultan lost their lives in the battle. The existing evidence of the additional stories and speculations as to how Murad I died were disseminated and recorded in the 15th century and later, decades after the actual event. One Western source states that during the first hours of the battle, Murad I was assassinated by Serbian nobleman and
knight Miloš Obilić by knife. Most Ottoman chroniclers (including
Dimitrie Cantemir) state that he was assassinated while he was inspecting the battlefield after the battle had finished. His older son
Bayezid, who was in charge of the left wing of the Ottoman forces, took charge after that. His other son,
Yakub Bey, who was in charge of the other wing, was called to the Sultan's command center tent by Bayezid, but when Yakub Bey arrived he was strangled, leaving Bayezid as the sole claimant to the throne. In a letter from the Florentine senate (written by
Coluccio Salutati) to the King
Tvrtko I of Bosnia, dated 20 October 1389, Murad I's (and Yakub Bey's) killing was described. A party of twelve Serbian lords slashed their way through the Ottoman lines defending Murad I. One of them, allegedly
Miloš Obilić, had managed to get through to the Sultan's tent and kill him with sword stabs to the throat and belly. Murad's internal organs were buried in Kosovo field and remain to this day on a corner of the battlefield in a location called
Meshed-i Hudavendigar which has gained a religious significance for the local Muslims. It was vandalized between 1999 and 2006 and was renovated. His other remains were carried to
Bursa, his
Anatolian capital city, and were buried in a tomb at the complex built in his name. == Appearance and character ==
