Description

Marie-Adélaïde (Marie Adelheid Thérèse Hilda Wilhelmine; 1894–1924), reigned as Grand Duchess of Luxembourg from 1912 until her abdication in 1919. She ruled through the First World War, and her perceived support for the German occupation forces led to great unpopularity in Luxembourg as well as neighbouring France and Belgium. In 1919, on the advice of Parliament and after enormous pressure from the Luxembourgish people, she abdicated on 14 January 1919 in favour of her younger sister Charlotte who managed to save the monarchy and the dynasty in a national referendum (28 September 1919).

Charlotte (Charlotte Adelgonde Élise/Elisabeth Marie Wilhelmine; 1896–1985) reigned as Grand Duchess of Luxembourg from 1919 until her abdication in 1964. She was the last agnatic member of the House of Nassau.
