Suppose the Belgium revolt of 1830 did not happen or did not materialize in a division of two small states.
This United Kingdom of the Netherlands evolves during the next 2 decades in an industrial nation with a nucleus of a colonial empire which was a left over of the Dutch East Indian Company and West Indian Company.
What effects on the balance of power would this nation have?
It is a mid sized power, even it will be one of the most industrialized nations of Europe with a very dense railroad network, the population base is relative low , how ever likely a bit larger as OTL and better educated.
Most likely, encouraged by commercial interest, the West African trade stations will renew their commercial values and even encourage further investments in the African continent, even opening of trade post in Southern Africa, facilitating Boer Republics?
The East Asian trade posts will be pacified faster, earlier in the 19th century, and, commercial, interest could encourage expansion.
Possible active participation with Chinese-European trade wars, like the opium wars.
Which effect o this overseas activities could have on the relations with Great Britain and France?
Economical/industrial power could have effect on German unification?
Would it involve with the Sleswick-Holstein wars or the Bruder Krieg if this wars happen at all.
