Brunette Girl Reveals Outside With A Sword And Knight's Armour

Outside the British honours system it is usually considered improper to address a knighted person as 'Sir' or 'Dame'. Some countries, however, historically did have equivalent honorifics for knights, such as Cavaliere in Italy (e.g. Cavaliere Benito Mussolini), and Ritter in Germany and the Austro-Hungarian Empire (e.g. Georg Ritter von Trapp).
State Knighthoods in the Netherlands are issued in three orders, the Order of William, the Order of the Netherlands Lion, and the Order of Orange Nassau. Additionally there remain a few hereditary knights in the Netherlands.
In France, among other orders are the Légion d'Honneur, the Ordre National du Mérite, the Ordre des Palmes académiques and the Ordre des Arts et des Lettres. The lowest of the ranks conferred by these orders is Chevalier, meaning Knight.
In the Polish-Lithuanian Commonwealth the monarchs tried to establish chivalric orders but the hereditary lords who controlled the Union did not agree and managed to ban such assemblies. They feared the King would use Orders to gain support for absolutist goals and to make formal distinctions among the peerage which could lead to its legal breakup into two separate classes, and that the King would later play one against the other and eventually limit the legal privileges of hereditary nobility. But finally in 1705 King August II managed to establish the Order of the White Eagle which remains Poland's most prestigious order of that kind. The head of state (now the President as the acting Grand Master) confers knighthoods of the Order to distinguished citizens, foreign monarchs and other heads of state. The Order has its Chapter. There were no particular honorifics that would accompany a knight's name as historically all (or at least by far most) its members would be royals or hereditary lords anyway. So today, a knight is simply referred to as "Name Surname, knight of the White Eagle (Order)".
