Saint Helen of Serbia was the queen consort of the Serbian Kingdom, as the spouse of King Stefan Uroš I, who ruled from 1243 to 1276. Their sons were later Serbian kings Stefan Dragutin and Stefan Milutin. As a dowager-queen, she held the provincial governorship in the regions of Zeta and Travunija. She built Gradac Monastery and was known for her religious tolerance. She is venerated as a saint by the Eastern Orthodox Church. Her relics, however, are now lost.
