 Traditionally , reigning European monarchs are admitted to the Order as Strangers . Constantine II , King of the Hellenes , neither in his short reign nor since he was deposed in 1973 , has succeeded his father Paul of Greece as a member of the Order . Similarly , Albert II , King of the Belgians and his son and successor Philippe are the only Belgian monarchs to date not to have been admitted to the Order . For a time , both Juliana , Queen of the Netherlands and her successor , Queen Beatrix were concurrently members of the Order as Stranger Ladies of the Garter .
