The Netherlands is part of the Kingdom of the Netherlands. This Kingdom also includes several islands in the Caribbean. Some are independent countries within the Kingdom, while others are part of the Netherlands. Here is how this works.

The Kingdom of the Netherlands consists of 4 countries

The Kingdom of the Netherlands consists of 4 countries: the Netherlands, Aruba, Curaçao and Sint Maarten. King Willem-Alexander is the head of state of the entire Kingdom.

The Netherlands is not limited to the European part that appears on the map next to Germany and Belgium. Bonaire, St. Eustatius and Saba are also part of the Netherlands. These three islands are located in the Caribbean and are collectively known as the Caribbean Netherlands.

The fact that the islands now have different statuses is due to choices made when the Netherlands Antilles were dissolved. Bonaire and Saba opted for a direct relationship with the Netherlands. Curaçao and Sint Maarten chose to become separate countries within the Kingdom. Sint Eustatius initially wanted to remain part of the Netherlands Antilles. When the Netherlands Antilles ceased to exist, Sint Eustatius also entered into a direct relationship with the Netherlands.

The biggest change took place on 10 October 2010. The Netherlands Antilles ceased to exist. Curaçao and Sint Maarten, like Aruba, became separate countries within the Kingdom. Bonaire, Sint Eustatius and Saba became part of the Netherlands.

The countries within the Kingdom handle many matters on their own

The Netherlands, Aruba, Curaçao and Sint Maarten each have their own government.

Aruba, Curaçao and Sint Maarten therefore set many of their own rules, for example regarding education, healthcare and taxes.

The countries handle certain matters jointly within the Kingdom. This applies, for example, to defence, foreign affairs and Dutch citizenship.

Bonaire, St. Eustatius and Saba are similar to Dutch municipalities

Bonaire, St. Eustatius and Saba are part of the Netherlands. They are often referred to as ‘bijzondere gemeenten’ (special municipalities). Officially, they are called

However, they may do so if, for example, they have lived in the Netherlands for at least 10 years. In that case, they must register as voters living outside the Netherlands.
