The Netherlands is the European part of the Kingdom of the Netherlands, which is formed by the Netherlands, the Netherlands Antilles and Aruba. The Netherlands is a constitutional monarchy, located in northwestern Europe. It is bordered by the North Sea to the north and west, Belgium to the south, and Germany to the east. The current borders were established in 1839. The Netherlands is often referred to by the name Holland. This is not terminologically precise, since the provinces of North and South Holland in the western Netherlands are only two of the country's twelve provinces. The Netherlands is a densely populated and geographically low-lying country (its name literally means "low countries" or "low lands") and is popularly known for its windmills, clogs (wooden shoes), dikes, tulips, bicycles and social tolerance. Its policies are liberal towards drugs, prostitution, same-sex marriage, abortion and euthanasia. The country is host to the International Criminal Tribunal for the Former Yugoslavia, the International Court of Justice and the International Criminal Court at The Hague.
