The unity of the Realm is acted out in the principle of "The Unity of the Realm".

Faroese or Greenlandic self-governance cannot be established by international treaties but must be established by Danish law; the Danish parliament (the Folketing) delegates a precisely defined part of its competence to the home rule authorities.
