The three above-mentioned Orders together with the Order of Vasa form the Orders of His Majesty the King (Swedish "Kungl. Maj:ts Orden"). A Swedish Knight of the Order of the Seraphim is not referred to as a Knight of the Seraphim, but rather as a "Knight and Commander of the Orders of His Majesty the King" (). This form is used because the Swedish word "orden" is an old plural form which indicates that a knight has to be a Commander Grand Cross or Commander of at least one of the other Swedish Orders. Foreign Knights are for the greater part Knights of the Order of the Seraphim. A Knight of the Order may be styled "Herr" + surname, which used to be the formal style for Swedish secular Knights (untitled high-ranking noblemen) appointed by the Swedish King, a practice that ceased in the 17th Century.
