Marie-Adélaïde, Grand Duchess of Luxembourg

Grand Duchess of Luxembourg from 1912 to 1919

Marie-Adélaïde (French: Marie-Adélaïde Thérèse Hilda Wilhelmine, Luxembourgish: Marie-Adelheid; 14 June 1894 – 24 January 1924), was Grand Duchess of Luxembourg from 1912 until her abdication in 1919. She was the first Grand Duchess regnant of Luxembourg (after five grand dukes), its first female monarch since Duchess Maria Theresa (1740–1780, who was also an Austrian archduchess and Holy Roman Empress) and the first Luxembourgish monarch to be born within the territory since Count John the Blind (1296–1346). Named as heiress presumptive by her father Grand Duke William IV in 1907 to prevent a succession crisis due to his lack of a son, Marie-Adélaïde became Grand Duchess aged 17 upon his death in 1912.
