Arenberg, also spelled as Aremberg or Ahremberg, is a former county, principality and finally duchy that was located in what is now Germany. The Dukes of Arenberg remain a prominent Belgian noble family.
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.
The pre-Napoleonic duchy had an area of 413 km² and a population of 14,800. It belonged to the Electoral Rhenish Circle and was bordered by the duchy of Jülich, the Archbishopric of Cologne, the Archbishopric of Trier, and the county of Blankenheim.
After the French occupation of the west bank of the Rhine around 1798 (see Treaty of Campo Formio and Treaty of Lunéville), the Duke of Arenberg received new lands: the county of Vest Recklinghausen, the county of Meppen, and the lordship of Dülmen.
Arenberg joined Napoleon's Confederation of the Rhine, although that did not prevent it from being mediatised in 1810, with France annexing Dülmen and Meppen, and the duchy of Berg annexing Recklinghausen.
After Napoleon's defeat in 1814 and the dissolution of the Confederation of the Rhine, the former Arenberg territories were divided between the kingdom of Prussia and the kingdom of Hanover. In both Prussia and Hanover, the dukes became local peers subordinate to the king.
In 1826, the Arenberg territory in Hanover was named the duchy of Arenberg-Meppen, and it had an area of 2,195 km² and a population of 56,700. The county of Recklinghausen, in Prussia, had an area of 780 km² and a population of 64,700.
The Dukes of Arenberg remain a prominent Belgian aristocratic family. The immediate family members of the dukes are called by the nominal title of Prince of Arenberg. The ducal family descends agnatically from the House of Ligne.
