Gothic tribes who remained in the lands around the Black Sea, especially in Crimea, were known as the Crimean Goths. During the late 5th and early 6th century, the Crimean Goths had to fend off hordes of Huns who were migrating back eastward after losing control of their European empire. In the 5th century, Theodoric the Great tried to recruit Crimean Goths for his campaigns in Italy, but few showed interest in joining him. They affiliated with the Eastern Orthodox Church through the Metropolitanate of Gothia, and were then closely associated with the Byzantine Empire.
