Lazar Hrebeljanović was a prominent medieval Serbian leader who governed the largest state following the fragmentation of the Serbian Empire. Born around 1329 in Prilepac, he rose from a court official to a powerful prince, ruling the Moravian Serbia region from 1371 until his death. He sought to unify the fractured territories and claimed a connection to the former Nemanjić dynasty. He is remembered for leading Christian forces against the Ottoman Empire, where he was killed during the Battle of Kosovo in 1389.
