The Principality of Theodoro, also known as Gothia (Γοτθία) or the Principality of Theodoro-Mangup, was a Greek principality in the southern part of Crimea, specifically on the foothills of the Crimean Mountains. It represented one of the final rump states of the Eastern Roman Empire and the last territorial vestige of the Crimean Goths until its conquest by the Ottoman Empire by the Ottoman Serb Gedik Ahmed Pasha in 1475. Its capital was Doros, also sometimes called Theodoro and now known as Mangup. The state was closely allied with the Empire of Trebizond.
