Gijsbert Karel van Hogendorp is the auctor intellectualis of the 1818 Dutch constitution. It was his sketch for a new constitution that was used as a starting point for the deliberations of its original drafting committee. Van Hogendorp justifies his constitution as a restoration of the Burgundian constitution that applied before the Dutch Republic. In recent literature Van Hogendorp’s restorational argument is presented as an invention of tradition. In this article an alternative explanation is presented, namely that it is part of a form of classicist political thought that was common during the ancien régime. Van Hogendorp describes his constitution as a moderate monarchy, in which the three principles of monarchy, aristocracy and democracy are properly balanced. And he mainly defends this mixed regime by pointing out that it is a restoration of the old Burgundian constitution of the Netherlands. This way of reasoning is, as will be shown, typically classicistic.
