Vlatko Vuković, the son of Vuk, brought the family to prominence after taking part in battles against the Ottomans. He commanded the victorious Bosnian army at the Battle of Bileća (1388). At the Battle of Kosovo (1389) Bosnian King Tvrtko I sent him to command with his troops. Bosnian contingent under Vlatko was positioned at the left flank from the Serbian army led by Prince Lazar of Serbia. The battle was at first reported as a victory, also by Vlatko himself, however it has been concluded as inconclusive, with a long-term Ottoman victory.
