Principality of Theodoro
former country on the Crimea Peninsula

The Principality of Theodoro (Greek: Αὐθεντία πόλεως Θεοδωροῦς καὶ παραθαλασσίας), also known as Gothia (Γοτθία) or the Principality of Theodoro-Mangup, was a principality in the southern part of Crimea, specifically on the foothills of the Crimean Mountains. It represented the final rump state of the Eastern Roman Empire and the last territorial vestige of the Crimean Goths until its conquest by the Ottoman Empire by the Ottoman 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.
Geography
The Theodoro principality wíth its capital Theodoro (also known as Mangup) was located in the Crimean Mountains in southern Crimea. From the first half of the 15th century it also included parts of the coastline, now stretching from Kalamita Bay in the west to possibly as far east as modern Rybache just west of Kanaka.
Nomenclature
The name "Theodoro" (in the corrupted form Θεοδωραω) appears for the first time in a Greek inscription also dated to c. 1361/1362, and then again as "Theodoro Mangop" in a Genoese document of 1374. It was suggested by A. Mercati that the form is a corruption of the Greek plural Theodoroi 'the Theodores', meaning Saints Theodore Stratelates and Theodore Tiro, but N. Bănescu proposed the alternative explanation that it resulted from the definitive Greek name τὸ Δόρος (to Doros) or τὸ Δόρυ (to Dory), after the early medieval name of the region. Whatever its provenance, the name stuck: by the 1420s the official titulature of the prince read "Lord of the city of Theodoro and the Maritime Region" (αὐθέντης πόλεως Θεοδωροῦς καὶ παραθαλασσίας), while colloquially it was called Θεοδωρίτσι (Theodoritsi, 'little Theodoro') by its inhabitants.
