The Thuringii or Toringi, were a Germanic tribe that appeared late during the Völkerwanderung in the Harz Mountains of central Germania still called Thuringia. It became a kingdom, which came into conflict with the Merovingian Franks, and it later came under their influence and Frankish control. The name is still used for one of modern Germany's federal states (Bundesländer).
The Thuringians do not appear in classical Roman texts under that name, but some have suggested that they were the remnants of the Suebic Hermanduri, the last part of whose name (-duri) could represent corrupted (-thuri) and the Germanic suffix -ing, suggests a meaning of "descendants of (the [Herman]duri)". This people were living near the Marcomanni. Tacitus in his "Germania", describes their homeland as being where the Elbe starts, but also having colonies at the Danube and even within the Roman province of Rhaetia.
Claudius Ptolemy mentions neither the Hermunduri nor the Thuringians in his geography but instead the Teuriochaemae, living in just north of the Sudetes mountains, thought to be the Erzgebirge. These may also be connected to later Thuringians. ("Chaemae" may represent a version of the Germanic word for "home". Ptolemy also mentions a people called the Bainochaimai to the west of the Elbe. He also apparently spells the name of the Chamavi in a similar way.) The formation of this people may have had also been influenced by two longer-known tribes more associated with the eastern bank of the lower Elbe river, northeast of Thuringia, because the Carolingian law code written for them was called the "law of the Angles and Varini that is the Thuringians". Much earlier, Tacitus in his "Germania", for example, had grouped these two tribes among the more distant Suebic tribes, living beyond the Elbe, and near a sea where they worshiped Herthus. (Pliny the Elder had listed the Varini as a Vandalic, or East Germanic tribe, rather than Suebian.) These two tribes are among Germanic groups known to have been found north of the Danube in this period. Procopius in his "Gothic Wars" describes the land of the Varini as being south of the Danes, but north of the Slavs, who were in turn north of unfarmed lands which lay north of the Danube. He also mentions a story about a marriage alliance between the Varini and the Angles in England, indicating long distance links.
