Stefan Uroš I, known as Uroš the Great was the King of Serbia from 1243 to 1276, succeeding his brother Stefan Vladislav. He was one of the most important rulers in Serbian history. During his reign the foundations were laid for the expansion of the Serbian medieval state, which would become an empire in the middle of the 14th century.

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.
