Counts of Vianden

In the 12th to 15th centuries the counts of Vianden were the mightiest lords of the area between the rivers Rhine, Mosel and Maas.

Their territory was in modern Vianden canton, Luxemburg and Bitburg-Prüm, Germany.

One recognition of their importance was that Henry I of Vianden (c. 1200–1252) in 1216 married Margaret, Marchioness of Namur (c. 1194–1270) of the Capetian House of Courtenay, and daughter of Peter II of Courtenay (1167–1217), emperor of Constantinople.

Godefroid I participated in the Battle of Worringen in 1288 as a vassal to the Duchy of Brabant.

Numberings and names can vary and the year details have several uncertainties and should be taken as approximative due to some conjecture in lack of complete documentation.
