House of Nassau

The House of Nassau is a diversified aristocratic dynasty in Europe. It is named after the lordship associated with Nassau Castle, located in present-day Nassau, Rhineland-Palatinate, Germany. The lords of Nassau were originally titled Count of Nassau, then elevated to the princely class as princely counts. At the end of the Holy Roman Empire, they proclaimed themselves Dukes of Nassau. All Dutch queens since 1890 and the Grand Dukes of Luxembourg since 1912 have been descended in the female line from the House of Nassau. According to German tradition, the family name is passed only in the male line of succession. The house is therefore, from this perspective, extinct since 1985.[1] However Dutch aristocratic customs (and Luxembourg's, which are based on the aforementioned) differ, and do not consider the House extinct.

Origins

Count Dudo-Henry of Laurenburg (ca. 1060 – ca. 1123) is considered the founder of the House of Nassau. He is first mentioned in the purported founding-charter of Maria Laach Abbey in 1093 (although many historians consider the document to be fabricated). The Castle Laurenburg, located a few miles upriver from Nassau on the Lahn, was the seat of his lordship. His family probably descended from the Lords of Lipporn. In 1159, Nassau Castle became the ruling seat, and the house is now named after this castle. The Counts of Laurenburg and Nassau expanded their authority under the brothers Robert (Ruprecht) I (1123–1154) and Arnold I of Laurenburg (1123–1148). Robert was the first person to call himself Count of Nassau, but the title was not confirmed until 1159, five years after Robert's death. Robert's son Walram I (1154–1198) was the first person to be legally titled Count of Nassau. The chronology of the Counts of Laurenburg is not certain and the link between Robert I and Walram I is especially controversial. Also, some sources consider Gerhard, listed as co-Count of Laurenburg in 1148, to be the son of Robert I's brother, Arnold I.[2] However, Erich Brandenburg in his Die Nachkommen Karls des Großen states that it is most likely that Gerhard was Robert I's son, because Gerard was the name of Beatrix of Limburg's maternal grandfather.[3]
