In a war in 1673, Louis XIV of France took over the lands of the principality and added them to his own royal domain. This was part of the war against the stadtholder William III of Orange. Louis XIV then gave the principality to Louis of Mailly-Nesles, marquis of Nesles (1689–1764), a very remote relation of the original princes of Orange. His descendant still claims the title today. In 1714, Louis XIV allowed Prince Louis Armand of Bourbon-Conti to use the land of the Principality to make money. Prince Louis Armand died in 1727 and the principality was merged in the Crown in 1731.
