Greuthungi

The Greuthungi (also spelled Greutungi) were a Gothic people who lived on the Pontic steppe between the Dniester and Don rivers in what is now Ukraine, in the 3rd and the 4th centuries.[1] They had close contacts with the Tervingi, another Gothic people, who lived west of the Dniester River. To the east of the Greuthungi, living near the Don river, were the Alans.

When the Huns arrived in the European Steppe region in the late 4th century, first the Alans were forced to join them, and then a part of the Greuthungi. Alans and Goths became an important part of Attila's forces, together with other eastern European peoples. Many Greuthungi, together with some Alans and Huns, crossed the Lower Danube to join a large group of Tervingi who had entered the Roman Empire in 376. These peoples defeated an imperial army in the Battle of Adrianople in 378, and came to a settlement agreement within the Roman empire by 382 AD. The original tribal names of the Goths fell out of use within the empire. Many of the 382 settlers appear to have become an important component of the Visigoths who formed under Alaric I.

Based upon interpretations of the Getica by the 6th century writer Jordanes, although it never mentions the Greuthungi, the Greuthungi are strongly associated with both the Gothic king Ermanaric, and the later Amal dynasty who were among Attila's Goths. After the collapse of Attila's empire, the Amals founded the Ostrogothic kingdom in the Roman Balkans.
