Theodore Komnenos Doukas
In 1228, Theodore Komnenos Doukas confirmed possession of lands "on the island of Corfu and the "thema" of Vagenetia" to the Metropolitan of Corfu. In 1292, the coasts of the province were raided by Genoese ships in Byzantine employ, and two years later, the province was promised to Philip of Taranto as part of the dowry of Thamar Angelina Komnene. Still, the Despot of Epirus Thomas I Komnenos Doukas was ascribed the title of "Duke of Vagenetia" in a Venetian document in 1313. In 1315, a document of the Patriarchate of Constantinople records that Vagenetia belonged to the bishopric of Himara.
