Angrivarii

The Angrivarii (or Angrivari) were a Germanic people of the early Roman Empire, who lived in what is now northwest Germany near the middle of the Weser river. They were mentioned by the Roman authors Tacitus and Ptolemy.

The approximate positions of some Germanic peoples reported by Graeco-Roman authors in the 1st century.

They were part of the Germanic alliance of Arminius and his defeat of the Romans at the Battle of the Teutoburg Forest in the 9th year of the common era.

The Angrivarii lived in an area which was later called Angria (Modern German "Engern") in the Middle Ages, which was a major part of the Carolingian Duchy of Saxony. Both names probably derive from geographical terminology.
