The Order of St. George – a European Order of the House of Habsburg-Lorraine (German: St. Georgs-Orden – ein Europäischer Orden des Hauses Habsburg-Lothringen), or simply Order of Saint George, is a dynastic order of chivalry and thus a house order of the House of Habsburg-Lorraine, the former Imperial and Royal House of the Holy Roman Empire, the Habsburg monarchy, the Empire of Austria, the Austro-Hungarian Monarchy, the Kingdom of Hungary, the Crown lands of Bohemia and Kingdom of Croatia-Slavonia and further nations.
The order combines knightly tradition with the idea of a united Europe in the sense of the political ideas of Archduke Otto von Habsburg. The roots of the order go back a long way, not in the sense of an uninterrupted continuity, but in the continuation of an ideal of Christian chivalry. The history of the Order in Central Europe begins in the Kingdom of Hungary in the 14th century, experienced its heyday as a Habsburg house order at the beginning of modern times, was reinterpreted after the end of the First World War and continued as a dynastic house order of the 21st century on behalf of Archduke Otto and his son Karl von Habsburg.
