Koblenz-Arenberg

Koblenz-Arenberg (also spelled as Aremberg or Ahremberg) is a historic duchy located in modern Germany. First mentioned in the 12th century, it was named after the village Aremberg in the modern district of Ahrweiler, in the Rhineland-Palatinate. The territorial possessions of the dukes of Arenberg varied through the ages. Around 1789 the duchy was located in the Eifel region on the west side of the Rhine, and contained amongst others Aremberg, Schleiden and Kerpen. However, although the Duchy itself was in Germany, from the 15th century on, the principal lands of the Dukes of Arenberg have been in modern day Belgium.
