the Netherlands gets a plural form in languages like English and French. I think this is because the official name of the entire country with it's colonies is "het koninkrijk der Nederlanden", the kingdom of the Netherlands. In the past, the country had many different names. The country was founded, when seven different regions made a pact to work together and they formed the republic of seven united Netherlands (Netherlands = low lands) But nowadays the Dutch call their country "Nederland", Netherland. Which means that the English and French language are a bit odd.
