Greek Authentía póleōs Theodoroús kaí parathalassías ("Lordship of the city of Theodoro and the Maritime Region"); also Gothia or Theodoro-Mangup. A Greek-Orthodox principality in southwestern Crimea, capital at Doros/Mangup, the last territorial vestige of the Crimean Goths and one of the final rump states of the Eastern Roman world. Closely allied with the Empire of Trebizond. First mentioned as a principality in the early 14th century; rulers included Demetrios (first recorded, c. 1362–68) and, on the eve of the fall, the Gabras/Palaiologos-connected dynasty. Devastated by Timur (1395), it recovered after his death (1404) to become a significant Black Sea power, profiting from Genoese instability. After the fall of Constantinople (1453), Morea (1460) and Trebizond (1461), Theodoro was the last independent Byzantine-Greek state. It fell in the Ottoman Crimean campaign of 1475: after a roughly three-to-five-month siege, Gedik Ahmed Pasha captured Mangup in December 1475; the last prince Alexander was taken to Constantinople and executed — extinguishing the last Byzantine successor state 22 years after 1453.
