The Dutch government (Gouvernement des Pays-Bas) is a parliamentary democracy, which according to the constitution of the Netherlands consists of the King (or Queen) as the head of state and the Council of Ministers.
The Kingdom of the Netherlands,commonly known as the Netherlands, is a sovereign state and constitutional monarchy with the large majority of its territory in Western Europe and with several small island territories in the Caribbean Sea, in the West Indies islands (Leeward Islands and Lesser Antilles).
The four parts of the kingdom—the Netherlands, Aruba, Curaçao and Sint Maarten—are constituent countries (landen in Dutch) and participate on a basis of equality as partners in the kingdom. In practice, however, most of the kingdom’s affairs are administered by the Netherlands—which comprises roughly 98% of the kingdom’s land area and population—on behalf of the entire kingdom. Consequently, the Caribbean Sea islands countries of Aruba, Curaçao, and Sint Maarten are dependent on the Netherlands for matters like foreign policy and defence, although they are autonomous to a certain degree, with their own parliaments.
The vast majority in land area of the constituent country of the Netherlands is located in Europe, with the exception of the Caribbean Netherlands: its three special municipalities (Bonaire, Saba, and Sint Eustatius) are located in the Caribbean Sea like the other three constituent countries.
