The Cugerni (or Cuberni or Guberni) were a Germanic tribal grouping with a particular territory within the Roman province of Germania Inferior, which later became Germania Secunda. More precisely they lived near modern Xanten, and the old Castra Vetera, on the Rhine. This part of Germania Secunda was called the Civitas or Colonia Traiana (polity or colony of Trajan), and it was also inhabited by the Betasii.[1][2]
