Louis of Nassau, Lord of De Lek and Beverweerd was a Dutch soldier.
Background
He was the illegitimate son of Margaretha van Mechelen and Maurice of Nassau, Prince of Orange, and so a collateral member of the House of Orange-Nassau. From his father he inherited the estate of Beverweerd. And when his older brother Willem died in 1627 he inherited his estate as well.
Career
He was a Lord of the heerlijkheid De Lek and Beverweerd. In 1632 he was advanced to Colonel and after 1635 was in charge of a regiment. In 1640 during the battle for Hulst he prevented the cannons from falling into enemy hands.
In the same year he was sent to Paris to advise the French king of the forthcoming marriage of the 14-year-old William II of Orange to the 9-year-old English Princess Mary Stuart.
Also, when the young Prince proceeded to England to fetch his bride, he was accompanied by Louis of Nassau. In 1643 he became General-Major and Governor of the city of Bergen-op-Zoom.
Louis was originally a supporter of his next of kin, the Princes of Orange. After the death of William II he made his peace with the anti-Orangist regents of the cities of the Dutch Republic and worked with the administration of Johan de Witt, becoming First Noble of Holland.
In 1658 Louis of Nassau became Governor of Den Bosch and in 1660 was sent as a special ambassador to England.
