We always have to explain our nationality. So why not explain it here and get you confused on a whole new level.

The Netherlands are formally called the United Kingdom of the Netherlands. It is a small area in the Northwest of Europe. In its history it has been occupied by Spain, France & Germany. Even the UK did a number of attempts. Unfortunately they failed. It would have made the list of occupying forces we kicked out of the country even more impressive.

Like Germany, the Netherlands were a alliance of small areas of land, lead by a duke, prince or count. These former more or less independent area's are now our provinces. We have 12 of them. North- and South Holland are the most densely populated areas. So most of the world thinks our country is called Holland. It's like calling the UK Kent, or the USA Dakota (or, like Holland, the other). Nelleke is from Gelderland, Rob from Utrecht. Our kids were born in South Holland. We live in Gelderland.

In the mid of the 19th century the Flanders region started a new state with some French speaking provinces. The (lack of) result is called Belgium. They're nice people, but as a country not really happy campers. The discussion of ending the state has been a topic for years. If the country collapses, we predict Brussels DC as an EU province like Washington DC.

Our language is Dutch, and English speaking people call us the Dutch. Most English speaking countries can't figure out the difference between Dutch, Deutch, Duits and Danes.

This is how it is:

We are Dutch from the Netherlands and speak Dutch (In Dutch: We are Netherlanders from Nederland and we speak Nederlands).

"Duits" is Dutch for German, like "Deutch" is German for German. Since the Germans are the last people that were kicked out of our country, we don't like to be compared with German people. (Otherwise we get along great). The difference between our languages is considerable for the trained ear.

Danes are from Denmark. They have different cheese and are located north from Germany.

Still with us? Then here's the extra stuff. One of our provinces is Friesland. They are bi-lingual. Fries is a language, different from Dutch of German. As a language, it is much closer related to English than Dutch is.
The good news is most of the Dutch speak some English.
The Netherlands had quite some colonies in the past (New York, Dutch Guyana, Indonesia to mention a few). Nowadays only 6  Caribbean isles are part of the Kingdom. They have a high independency, if only for their distance to the Hague.
