The Principality of Theodoro, also known as Gothia , was a small principality in the south-west of Crimea and both a final rump state of the Eastern Roman Empire and vestige of the Crimean Goths until its conquest by the Ottoman Turks in 1475. Its capital was Doros, which was also sometimes called Theodoro and is now known as Mangup. The state was closely allied with the Empire of Trebizond and was distinctive for its East Germanic (albeit heavily Hellenized) population.
