Stephen Vladislav I of Serbia

Stefan Vladislav was the King of Serbia from 1234 to 1243. He was the middle son of Stefan the First-Crowned of the Nemanjić dynasty, who ruled Serbia from 1196 to 1228. Radoslav, the eldest son of Stefan the First-Crowned, was ousted by the Serbian nobility due to increasing Epirote influence through his marriage alliance to Theodore Komnenos Doukas; thus Vladislav became his successor. He is celebrated as Saint Vladislav by the Serbian Orthodox Church on September 24 [O.S. October 7].
