Stefan Uroš I of Serbia

Stefan Uroš I, Uroš the Great (c. 1223–1 May 1277), was the youngest son of Stefan the First-Crowned and Anna Dandolo, granddaughter of the Venetian doge Enrico Dandolo. Chosen by the nobility, he replaced his half-brother Stefan Vladislav in 1243 after a brief succession war and ruled until 1276.

He gave Vladislav the administration of Zeta and married Helen, with whom he had sons Dragutin and Milutin. His long reign brought a mining boom that laid the groundwork for later Serbian expansion; he was also the first Serbian ruler to wear the full ceremonial vestments of Byzantine emperors. In 1276 conflict with his son Stefan Dragutin forced him to abdicate, and he died on 1 May 1277.
