Romanos I (27 February 1768 - 22 May 1828), known as the Great and as the Liberator, was the son of Symeon III Anemas and his wife Eirene Paphlagon. Originally the Bey of the Ottoman province of Anatolia, he became the first King of modern Nicaea, as well as the first Co-Regent of Constantinople after the Nicaean-Ottoman War. He married Theodora Psellina, and had two children with her - Alexios and Romanos, who would both become Kings of Nicaea. Upon his death in 1828, Romanos was succeeded by his firstborn son Alexios I.
