Wer heiratete William I of the Netherlands?

William I (Willem Frederik; 24 August 1772 – 12 December 1843) was King of the Netherlands and Grand Duke of Luxembourg from 1815 until his abdication in 1840.

Born as the son of William V, Prince of Orange, the last stadtholder of the Dutch Republic, and Wilhelmina of Prussia, William experienced significant political upheavals early in life. He fought against the French invasion during the Flanders campaign, and after the Batavian Revolution in 1795, his family went into exile. He briefly ruled the Principality of Nassau-Orange-Fulda before Napoleon's French troops' occupation forced him out of power. Following the defeat of Napoleon in 1814, William was invited back to the Netherlands, where he proclaimed himself Sovereign Prince of the United Netherlands.

In 1815, William raised the Netherlands to a kingdom and concurrently became the grand duke of Luxembourg. His reign saw the adoption of a new constitution, which granted him extensive powers. He was a strong proponent of economic development, founding several universities and promoting trade. However, his efforts to impose the Reformed faith and the Dutch language in the mostly Catholic and partly French-speaking southern provinces, combined with economic grievances, sparked the Belgian Revolution in 1830. Unable to suppress the rebellion, William ultimately accepted Belgian independence in 1839 under the Treaty of London.

William's later years were marked by dissatisfaction with constitutional changes and personal reasons, leading to his abdication in 1840 in favor of his son, King William II. He spent his final years in Berlin, where he died in 1843.
