The Corps was founded on 10 December 1665 during the Second Anglo-Dutch War by the unofficial leader of the republic Johan de Witt and Admiral Michiel de Ruyter as the Regiment de Marine. Its leader was Willem Joseph Baron van Ghent. The Dutch had successfully used ordinary soldiers in ships at sea in the First Anglo-Dutch War. It was the fifth European marine unit formed, being preceded by the Spanish Marines (1537), the Portuguese Marines (1610), the French Marines (1622) and the English Royal Marines (1664). Like Britain, the Netherlands has had several periods when its Marines were disbanded. The Netherlands itself was under French occupation or control from 1810 until 1813. A new marine unit was raised on 20 March 1801 during the time of the Batavian Republic and on 14 August 1806 the Korps Koninklijke Grenadiers van de Marine was raised under King Louis Bonaparte. The modern Korps Mariniers dates from 1814, receiving its current name in 1817.
