The Metropolitanate of Gothia (also of Gothia and Caffa), also known as the Eparchy of Gothia or Metropolitanate of Doros, was a metropolitan diocese of the Patriarchate of Constantinople in the Middle Ages.
The 9th-century Metropolitanate of Doros was centered in the Crimea, but it seems to have had dioceses further afield, as far east as the Caspian coast, but they were probably short-lived, as the Khazars converted to Judaism. From the 13th century until the Ottoman conquest in 1475, the Metropolitanate of Gothia was within the Principality of Theodoro (known in Greek as Γοτθία, Gothia). In 1779, it was transferred to the Russian Orthodox Church and disestablished a few years later.[1]
