What northwestern European country has two names and two separate capital cities?

Answer 1

You may be thinking of the Netherlands. It is sometimes called Holland, but that in fact is only a region of the Netherlands, and not a name for the whole country. So in reality, the Netherlands is the only name for the whole country. In terms of its capital, it only has one capital, which is Amsterdam. However, the seat of government and its Supreme Court are in the Hague, but it is not the capital. So despite these confusions, the country has only one name and only one capital.
