Principality of Theodoro
Medieval "Gothia" was still far from uniformly Gothic-speaking. Many "Crimean Goths" were Greek speakers and many non-Gothic Byzantine citizens were settled in the region called "Gothia" by the government in Constantinople. The official language of the Principality of Theodoro was Greek, but the Gothic language remained in use in private homes at least until the 18th century (Ogier Ghiselin de Busbecq in the 16th century reported having had a conversation with two Goths in Constantinople, and left a Gothic-Latin glossary with about a hundred Gothic words), but it is unknown for how long the Gothic language survived as liturgical language in the Crimean Gothic church.
