The Battle of Kosovo took place on 15 June 1389 between an army led by the Serbian Prince Lazar Hrebeljanović and an invading army of the Ottoman Empire under the command of Sultan Murad Hüdavendigâr.

The medieval period in the history of Serbia began in the 6th century with the Slavic migrations to Southeastern Europe, and lasted until the Ottoman conquest of Serbian lands in the second half of the 15th century. The period is also extended to 1537, when Pavle Bakić, the last titular Despot of Serbia in Hungarian exile, fell in the Battle of Gorjani.
