William II,(Wilhelm Frederik: Georg Lodewijk), king of the Netherlands and grand duke of Luxemburg, born Dec. 6, 1792, died March 17,1849. He studied in Berlin and Oxford, and in 1811 distinguished himself under Wellington in Spain, and in 1815 at QuatreBras, where he commanded, and at Waterloo, where he was wounded. In 1816 he married the Russian grand duchess Anne, a sister of Alexander I. In 1830 he went to Antwerp, and thence to Brussels, to arrange a peaceful settlement with the revolted Belgians, and on Oct. 16 recognized their independence. This act was repudiated by the king, and the prince was recalled and went to England. Subsequently he commanded the Dutch army against the Belgians, and in August, 1832, he was obliged to retreat before the French. He succeeded his father on the throne in 1840. In 1848, after the French revolution, he was constrained to liberalize the constitution still further, and to grant extensive reforms. The queen died on March 1, 1865; she had borne him a daughter, the present grand duchess of Saxe-Weimar-Eisenach, and two sons, his successor William, and Prince Henry, born June 13, 1820, who became lieutenant admiral, and in 1850 governor of Luxemburg.
