The Kingdom of the Netherlands, commonly known simply as the Netherlands, is a sovereign state consisting of a collection of constituent territories united under the monarch of the Netherlands, who functions as head of state. The realm is not a federation; it is a unitary monarchy with its largest subdivision, the eponymous Netherlands, predominantly located in Northwestern Europe and with several smaller island territories located in the Caribbean.
The four subdivisions of the KingdomâAruba, Curaçao, the Netherlands, and Sint Maartenâare constituent countries (landen in Dutch; singular: land) 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 Netherlandsâwhich comprises roughly 98% of the Kingdom's land area and populationâon behalf of the entire Kingdom. Consequently, Aruba, Curaçao, and Sint Maarten are dependent on the Netherlands for matters like foreign policy and defence, but are autonomous to a certain degree, with their own parliaments.
