Marko Mrnjavčević was born about 1335, in Livno, Kingdom of Serbia (now Bosnia and Herzegovina), the first son of Vukašin Mrnjavčević and his wife Jelena. Marko’s father, Vukašin, was king of the southern Serbian lands whose capital was Prilep (now in Macedonia).
When Vukašin was slain in battle with the Turks in 1371, Marko succeeded him as king but as a vassal to the Ottoman sultan. Marko is known to have completed a monastery at Sušica, near Skopje (Maced. ), and to have died fighting at the Battle of Rovine (May 25, 1395) during a war between the Turks and the Walachian prince Mircea the Old, but otherwise his life is sparsely documented. More colourful details have been preserved in Serbian ballads and epic poetry, as well as in various Balkan folk songs.
He is supposed to have lived for 300 years, to have ridden a horse 15 years old, and to have used his enormous physical strength against oppressors, especially against the Turks.
