[1] The Kingdom of the Netherlands was proclaimed on 16 March 1815, as a state in personal union with the Grand Duchy of Luxembourg under William I, a member of the House of Orange-Nassau who had already inherited a vast number of titles and lands from his ancestors.
[1] In 1866, however, the Duchy of Limburg ceased to exist as a separate polity and instead became integrated into the Kingdom of the Netherlands as a province.
His only surviving child and successor, Wilhelmina, married Duke Henry of Mecklenburg-Schwerin on 7 February 1901 and, as customary, assumed the feminine form of her husband's title.
[3] Her only child, Juliana, was therefore born not only duchess of Mecklenburg but also princess of Orange-Nassau, like previous members of the Dutch royal family.
[4] On 4 September 1948, Wilhelmina abdicated in favour of Juliana, which brought the title of princess of Lippe-Biesterfeld into the full style of the Dutch monarch.
