Swedish freemasons can in rare cases be awarded with the Order of Charles XIII. This is a Royal order of chivalry, equivalent to a knighthood and given only to Knights-Commander of the Red Cross at the King's pleasure; its members may not number more than thirty-three, and three of them must be ecclesiastics of the established Lutheran Church. Although it is jokingly termed the 'twelfth degree', the Order of Charles XIII is in no way a part of the official Swedish Rite, and is not classed as a masonic degree.
