Marko Mrnjavcevic (, ; – 17 May 1395) was the
de jure Serbian king from 1371 to 1395, while he was the
de facto ruler of territory in western
Macedonia centered on the town of
Prilep. He is known as
Prince Marko (,
Kraljevic Marko, ) and
King Marko (; ) in
South Slavic oral tradition, in which he has become a major character during the period of
Ottoman rule over the
Balkans. Marko's father, King
Vukašin, was co-ruler with Serbian
Tsar Stefan Uroš V, whose reign was characterised by weakening central authority and the gradual disintegration of the
Serbian Empire. Vukašin's holdings included lands in western Macedonia,
Kosovo and
Metohija. In 1370 or 1371, he crowned Marko "young king"; this title included the possibility that Marko would succeed the childless Uroš on the Serbian throne.
