The noble prince was married to Kosara, a daughter of the Bulgarian Tsar Samuel. Summoned for talks with the Bulgarian Tsar John-Vladislav, he was treacherously murdered by the Tsar on May 22, 1015, at the entrance to a church. Kosara, the pious spouse of the holy prince, entered a women’s monastery that she built, and where also she died, not leaving the church until the very end of her life. The relics of the holy prince are located near Elbosan.
