In 2011 Grand Duke Henri decreed that his female descendants would henceforth enjoy the right of succession to the throne without regard to gender, in accordance with absolute primogeniture. Other princesses of the dynasty, descended from prior sovereigns, may still inherit the throne in the event of extinction of all male dynasts and of all dynasts descended from Grand Duke Henri, and in the order stipulated by the 1907 amendment to the 1783 Nassau Family Pact
