Netherlands
Most Dutch people refer to their country as themselves as 'Nederlanders' for the people and 'Nederlands' for the language. Since Dutch (th … e language) is 'Nederlands' in Dutch and the people are 'Nederlanders' in Dutch. So they had to do something and they named the people from Deutschland Germans and they kept using Dutch for people from Nederland. Because the Dutch were more important in that time (for the English) than the Germans they gave the Germans a different name (the most important keeps the name). However, I’ve been studying Dutch for a while now which is also how I happened to come across this article. Anyway, here we call the people from the Netherlands “nederlaendere” nederlændere “or” hollaendere hollændere and “The/Country” nederland “Nederlandene”.

Often the Netherlands is called Holland, but this is only part of the Netherlands. One can count all people living the Netherlands as Dutch, but this is often not the case. This is because many people who live in The Netherlands were not born there. There are about 15.5 million people in the Netherlands who actually have the Dutch nationality. “Low Dutch” referred to people from the flatlands in what is now the Netherlands. Within the Holy Roman Empire, the word “Netherlands” was used to describe people from the low-lying (nether) region (land).

They share a common culture and speak the Dutch language. Dutch people and their descendants are found in migrant communities worldwide, notably in Suriname, Curacao, Curaçao, Argentina, Brazil, Canada, Australia South, Africa New, zealand and The United. states The origins of the word Dutch go back to Proto-Germanic, the ancestor of all Germanic languages, *theudo (meaning national/popular); akin to Old Dutch dietsc, Old High German diutsch, Old English þeodisc and Gothic þiuda all meaning (of) the common (Germanic) people.
