- William IV, Grand Duke of Luxembourg
William IV, Grand Duke of Luxembourg (Guillaume Alexandre) (
April 22 ,1852 –February 25 ,1912 ) was the eldest child ofAdolphe, Grand Duke of Luxembourg . He became Grand Duke on the death of his father onNovember 17 ,1905 .William IV was a Protestant, the religion of the
House of Nassau . He married Marie Anne of Portugal, believing that a Roman Catholic country ought to have a Roman Catholic monarch. Thus since William IV all other Grand Dukes have been Catholic.At the death of his uncle, Prince Nikolaus-Wilhelm in 1905, the only other legitimate male in the House of Nassau-Weilburg was Guillaume's cousin, Georg Nikolaus,
Count of Merenberg , the product of amorganatic marriage. So in 1907, Guilliame declared the Counts of Merenberg non-dynastic, naming his own eldest daughter Marie-Adélaïde (1894–1924) as heir to the grand ducal throne. She became Luxembourg's first reigning female monarch 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 have reigned until the present day.Family
