Who married William III of the Netherlands?

William III (Dutch: Willem III, French: Guillaume III; 19 February 1817 – 23 November 1890) was King of the Netherlands and Grand Duke of Luxembourg from 1849 until his death in 1890, and was also the Duke of Limburg from 1849 until the abolition of the duchy in 1866. Having reigned for 41 years, he is the second-longest reigning Dutch monarch, only surpassed by his daughter, Wilhelmina.

William was the son of King William II and Anna Pavlovna of Russia. On the abdication of his grandfather William I in 1840, he became the Prince of Orange. On the death of his father in 1849, he succeeded as king of the Netherlands.

William married his cousin Sophie of Württemberg in 1839 and they had three sons, William, Maurice, and Alexander, all of whom predeceased him. After Sophie's death in 1877 he married Emma of Waldeck and Pyrmont in 1879 and they had one daughter Wilhelmina, who succeeded William to the Dutch throne. Meanwhile, being the last agnatic dynastic descendant of Otto I, Count of Nassau, the throne of the Grand Duchy of Luxembourg passed to his patrilineal seventeenth cousin once removed (and matrilineal third cousin), Adolphe. As of 2025, he is the last Dutch monarch to die whilst on the throne as all of his successors have abdicated in favor of their children.

Sophie av Württemberg, född 17 juni 1818 i Stuttgart, död 3 juni 1877 i Haag, drottning av Nederländerna 1849–1877. Dotter till kung Vilhelm I av Württemberg och Katarina Pavlovna av Ryssland.

Emma of Waldeck and Pyrmont (Adelheid Emma Wilhelmina Theresia; 2 August 1858 – 20 March 1934) was Queen of the Netherlands and Grand Duchess of Luxembourg as the wife of King-Grand Duke William III. An immensely popular member of the Dutch Royal Family, Queen Emma served as regent for her daughter, Queen Wilhelmina, during the latter's minority from 1890 until 1898.
