[4] Succession to the throne was governed by Salic law, as dictated by the Nassau Family Pact, first adopted on 30 June 1783.

[1] The right to reign over Luxembourg was until June 2011 passed by agnatic-cognatic primogeniture within the House of Nassau, as stipulated under the 1815 Final Act of the Congress of Vienna and as confirmed by the 1867 Treaty of London.

[1] The Nassau Family Pact itself can be amended by the usual legislative process, having been so on 10 July 1907 to exclude the Count of Merenberg branch of the House, which was descended from a morganatic marriage.

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.

Charlotte's descendants have since reigned as the continued dynasty of Nassau, and also constitute a cadet branch of the House of Bourbon-Parma.
