The Nemanjić House
Vladislav belonged to the Nemanjić dynasty, the line that shaped the medieval Serbian state and gave the Serbian Church several of its most venerated figures. He was the son of King Stephen the First-Crowned and a grandson of Stefan Nemanja, who is venerated as Saint Symeon the Myrrh-gusher. His uncle was Saint Sava, the first Archbishop of Serbia.
By tradition Vladislav married Beloslava, a daughter of the Bulgarian tsar Ivan Asen II, a union that bound the Serbian and Bulgarian courts. After a period of rule he gave way to his younger brother, and later sources record that he was given charge of the maritime lands of the Serbian realm.
