That's all the great achievements I can find.
And the Dutch were the only ones in modern times to occupy parts of England. What Hitler or Napoleon couldn't do, the Dutch did. And I say that just because you are British. It is not that big an achievement, because the Netherlands were for a little while the masters of the seas, followed by England. And if you have a bigger and more powerful fleet then England, then invasion is easy.
I do think the Netherlands should be in an expansion. Certainly not in the original. Germany, Russia, China or Egypt are way more important, but after the first 15 logical civs then the Netherlands should be one of the first of the smaller (not only in size, but more in importance) to be in an expansion. Ofcourse the Dutch were vital in economical history. Shares, stockmarkets, world trade: all that was catapulted by the Dutch. England took over that role. Quite easy, because when Holland was invaded (1672) by Munster, Cologne but most importantly France England took away the Dutch colonies. Ironically the English were utterly defeated by the Dutch at sea so they had to cancel any invasions and let the Germans and French to all the hard work. Then they took all the goodies in the form of a lot of colonies. Very well job indeed.
And then there is culture. I think after Italy (which has the largest influence on art-history in the world by far) the Netherland could be one of the most influental countries. Rembrandt and van Gogh are just two of the Dutch masters who represent a whole era of art. What Rommel is for warfare and Shakespeare is to literature, van Gogh is for modern art.
