What is "thuringii"

The Thuringii or Toringi were a Germanic tribe that appeared late during the Völkerwanderung in the Harz Mountains of central Germania, in a region that still bears their name to this day, Thuringia. It became a kingdom, which came into conflict with the Merovingian Franks, and it later came under their influence and Frankish control. Today, the name is still used for one of modern Germany's federal states ( Bundesländer).
