House of Orange-Nassau House of Nassau-Weilburg Under the 1783
Nassau Family Pact, Luxembourg and
Nassau — the Nassau family's territories within the
Holy Roman Empire — were governed by semi-
Salic law succession law, which permitted
inheritance through the female line only upon the total extinction of male members of the
dynasty. The Netherlands, however, was not party to this pact and operated under its own succession rules. When
William III died leaving only his daughter
Wilhelmina as an heir in 1890, these two frameworks produced divergent outcomes: Wilhelmina inherited the Dutch crown under Dutch law without restriction, while the crown of Luxembourg passed instead to
Adolphe, the dispossessed
Duke of Nassau and head of the
branch of Nassau-Weilburg — since he, as a surviving male of the dynasty, precluded female succession under the Family Pact. In 1905, Grand Duke Adolphe's younger half-brother, Prince
Nikolaus Wilhelm of Nassau, died, having left a son
Georg Nikolaus, Count von Merenberg who was, however, the product of a
morganatic marriage, and therefore not legally a member of the House of Nassau. In 1907, Adolphe's only son,
William IV, Grand Duke of Luxembourg, obtained passage of a law confirming the right of his eldest daughter,
Marie-Adélaïde, to succeed to the throne in virtue of the absence of any remaining
dynastic males of the House of Nassau, as originally stipulated in the Nassau Family Pact. She became the grand duchy's first reigning female monarch upon her father's death in 1912, and upon her own
abdication in 1919 was succeeded by her younger sister
Charlotte, who married
Felix of Bourbon-Parma, a prince of the former
Duchy of Parma. Charlotte's descendants have since
reigned as the continued dynasty of
Nassau.
House of Luxembourg-Nassau The
House of Luxembourg-Nassau originated in 1919 with the marriage of Grand Duchess Charlotte, Grand Duchess of Luxembourg (of the
House of Nassau‑Weilburg) to
Prince Félix of Bourbon‑Parma (of the
House of Bourbon-Parma). Their eldest son,
Jean, Grand Duke of Luxembourg (born 5 January 1921), succeeded to the throne in 1964, thus establishing the present ruling dynasty. Although the male‑line (agnatic) descent is from Bourbon‑Parma, the dynasty continues to be styled “Luxembourg‑Nassau” to reflect the historic Nassau‑Weilburg legacy maintained through Charlotte and the links with Luxembourg. ==Grand ducal consorts==
