Constituent countries of the Danish Realm
The Danish Realm is a sovereign state and personal union of three constituent countries, each of which share the Danish monarch as their head of state. The three constituent countries are:
All three constituent countries each have their own prime minister, who is the head of government and elected via the parliamentary system. The Danish monarchy is based in Copenhagen, the capital of Denmark, and as such exercises the monarch's power as head of state of Denmark directly. The Danish Antilles and Faroe Islands, on the other hand, each have a governor-general of their own, who is appointed by the Danish monarch on advice of their prime minister, each of whom represents the Danish monarchy in their respective constituent country.
While the three constituent countries are for the most part fully sovereign, in that they may enter into (non-military) international treaties and agreements, the Danish Defence is responsible for the military defence of all three constituent countries of the Danish Realm. Otherwise, each constituent country has its own government including domestic security apparatus.
