TaifalsThe Taifals or Tayfals (Taifali, Taifalae or Theifali; Taïfales) were a people group of Germanic or Sarmatian origin, first documented north of the lower Danube in the mid third century AD. They experienced an unsettled and fragmented history, for the most part in association with various Gothic peoples, and alternately fighting against or for the Romans. In the late fourth century some Taifali were settled within the Roman Empire, notably in western Gaul in the modern province of Poitou.
GreuthungiThe 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. 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.
ThervingiThe Thervingi, Tervingi, or Teruingi (sometimes pluralised Tervings or Thervings) were a Gothic people of the plains north of the Lower Danube and west of the Dniester River in the 3rd and the 4th centuries. They had close contacts with the Greuthungi, another Gothic people from east of the Dniester, and they also had significant interactions with the Roman Empire. They were one of the main components of the large movement of Goths and other peoples over the Danube in 376, and they are seen as one of the most important ancestral groups of the Visigoths.
FritigernFritigern (fl. 370s) was a Thervingian Gothic chieftain whose decisive victory at Adrianople during the Gothic War (376–382) led to favourable terms for the Goths when peace was made with Gratian and Theodosius I in 382. Fritigern appears in the Latinized form Fritigernus. The Gothic name is reconstructed as *Frithugairns "desiring peace". The Germanized name under which Fritigern is honored in the Walhalla temple (1842) is Friediger.
VisigothsThe Visigoths (ˈvɪzɪɡɒθs; Visigothi, Wisigothi, Vesi, Visi, Wesi, Wisi) were a Germanic people united under the rule of a king and living within the Roman Empire during late antiquity. The Visigoths first appeared in the Balkans, as a Roman-allied barbarian military group united under the command of Alaric I. Their exact origins are believed to have been diverse but they probably included many descendants of the Thervingi who had moved into the Roman Empire beginning in 376 and had played a major role in defeating the Romans at the Battle of Adrianople in 378.
ValensValens (Ouálēs; 328 – 9 August 378) was Roman emperor from 364 to 378. Following a largely unremarkable military career, he was named co-emperor by his elder brother Valentinian I, who gave him the eastern half of the Roman Empire to rule. In 378, Valens was defeated and killed at the Battle of Adrianople against the invading Goths, which astonished contemporaries and marked the beginning of barbarian encroachment into Roman territory. As emperor, Valens continually faced threats both internal and external.
FoederatiFoederati (ˌfɛdəˈreɪtaɪ, singular: foederatus ˌfɛdəˈreɪtəs) were peoples and cities bound by a treaty, known as foedus, with Rome. During the Roman Republic, the term identified the socii, but during the Roman Empire, it was used to describe foreign states, client kingdoms or barbarian tribes to which the empire provided benefits in exchange for military assistance. The term was also used, especially under the empire, for groups of "barbarian" mercenaries of various sizes who were typically allowed to settle within the empire.
GothsThe Goths (𐌲𐌿𐍄𐌸𐌹𐌿𐌳𐌰; Gothi, Gótthoi) were Germanic people who played a major role in the fall of the Western Roman Empire and the emergence of medieval Europe. In his book Getica (c. 551), the historian Jordanes writes that the Goths originated in southern Scandinavia, but the accuracy of this account is unclear. A people called the Gutones - possibly early Goths - are documented living near the lower Vistula River in the 1st century, where they are associated with the archaeological Wielbark culture.
Germanic peoplesThe Germanic peoples were historical groups of people that once occupied Northwestern and Central Europe and Scandinavia during antiquity and into the early Middle Ages. Since the 19th century, they have traditionally been defined by the use of ancient and early medieval Germanic languages and are thus equated at least approximately with Germanic-speaking peoples, although different academic disciplines have their own definitions of what makes someone or something "Germanic".
ArianismArianism (Ἀρειανισμός, Areianismós) is a Christological doctrine first attributed to Arius (AD 256–336), a Christian presbyter from Alexandria, Egypt. Arian theology holds that Jesus Christ is the Son of God, who was begotten by God the Father with the difference that the Son of God did not always exist but was begotten/made before "time" by God the Father; therefore, Jesus was not coeternal with God the Father, but nonetheless Jesus began to exist outside time as time applies only to the creations of God.
