The Royal Netherlands Army had a long and celebrated horse cavalry tradition that included three historic hussar (huzaren) regiments (Regiment Huzaren 1st Van Sytzama, 2nd Prins van Oranje and 3rd Prins Alexander), dating back to cuirassier units first organized by Napoleon back in 1810 (though other Dutch cavalry units went back much further).
