The Order is led by its thirty-seventh "Herrenmeister" ("Master of the Knights" or Grand Master), Prince Oskar of Prussia. Each of its knights, about four thousand men worldwide, is either a Knight of Justice ("Rechtsritter") or a Knight of Honor ("Ehrenritter"). Membership in the Order is by invitation only, and individuals may not petition for admission; it is not limited to German citizens or German speakers, and knights include citizens and residents of most major nations. Although membership is no longer limited to the nobility, as it was until 1948, the majority of knights still are drawn from this class. The Order comprises seventeen commanderies in Germany, one each in Austria, Finland, France, Hungary, and Switzerland, and a global commandery with subcommanderies in twelve other countries (Australia, Belgium, Canada, Colombia, Denmark, Italy, Namibia, Poland, South Africa, the United Kingdom, the United States, and Venezuela).
