Grand Duke Of Luxembourg Wllem Iv

Luxembourgish Grand Duke who reigned from 17 November 1905 until his death. Wëllem (German: Wilhelm, English: William, French: Guillaume) succeeded his father, Adolphe. At the death of his uncle, Prince Nikolaus-Wilhelm in 1905, the only other legitimate male in the House of Nassau-Weilburg was Wëllem's cousin, Georg Nikolaus, Count of Merenberg, the product of a morganatic marriage. So in 1907, Wëllem declared the Counts of Merenberg non-dynastic, naming his own eldest daughter Marie-Adélaïde (1894–1924) as heir presumptive to the grand ducal throne. She became Luxembourg's first reigning grand duchess upon her father's death in 1912, and upon her own abdication in 1919, was succeeded by her younger sister Charlotte (1896–1985). Charlotte's descendants reign until the present day. On 21 June 1893 in Fischhorn Castle, Zell am See, Wëllem married Infanta Marie Anne of Portugal, daughter of the Usurper Miguel of Portugal and Adelaide of Löwenstein-Wertheim-Rosenberg. The couple had six daughters. Wëllem was the last monarch of Luxembourg to die whilst still on the throne. He died on 25 February 1912, aged 59, at Berg Castle. Link to Wikipedia biography
