Marko Mrnjavcevic (referred to also as Prince Marko and King Marko) was a Serbian ruler who lived during the 14th century. Although Marko is said to have had the opportunity to inherit the throne of the Serbian Empire, he was not able to achieve this as a result of the Ottoman invasions. Whilst Marko succeeded his predecessor as a ruler, he became an Ottoman vassal. Many legends and folk stories have been built around Mrnjavcevic, turning him into a great hero not only in the literature and tradition of the Serbians, but also in those of the Southern Slavic peoples....
