Ostrogoths
The Ostrogoths (Latin: Ostrogothi or Austrogothi) were a branch of the later Goths (the other major branch being the Visigoths). The Ostrogoths, under Theodoric the Great, established a kingdom in Italy in the late 5th and 6th centuries. The Ostrogoths traced their origins to the Greutungi and a semi-legendary kingdom north of the Black Sea in the 3rd and 4th centuries. Migrating southward from the Baltic Sea, the Ostrogoths, at the time known as the Greuthungi, built up a huge empire stretching from the Dniester to the Volga River and from the Black Sea to the Baltic shores. The Ostrogoths were probably literate in the 3rd century, and their trade with the Romans was highly developed. Their Danubian kingdom reached its zenith under King Ermanaric, who is said to have committed suicide at an old age when the Huns attacked his people and subjugated them in about 370.
After their subjugation by the Huns, little is heard of the Ostrogoths for about 80 years, after which they reappear in Pannonia on the middle Danube River as federates of the Romans. However, a pocket remained behind in the Crimea when the bulk of them moved to central Europe, and these Crimean Ostrogoths existed until at least the 16th century.
