House of Limburg
The House of Limburg (in german: Haus von Limbourg) was a dynasty which can be traced back in the male line as far as Henry, count of Limburg, whose mother Jutta was heiress of Frederick, Duke of Lower Lorraine in the House of Ardenne–Luxembourg. Henry was also related to the counts of Arlon. Waleran I was probably his father-in-law rather than his father.
By marriage, the family acquired:
- The county of Luxemburg in 1214, which then passed to a younger branch, the House of Luxemburg.
- The county of Berg in 1218.
In 1288, the family lost the duchy of Limburg, which was conquered by John I, duke of Brabant. The elder branch, holding the county of Berg, died out in 1348. The younger branch of Luxembourg acceded to the Empire.
