Assuming William III of Orange-Nassau has a son at some point (I choose 1695 with the assumption that Mary II survives smallpox and William III views her brush with death as a defining moment for himself, gives up the mistresses, and focuses on her) what happens? (I'm asking mostly since I just don't know enough about the era, and am working on a timeline.)
First off I'm specifically turning down the union of England & the United Provinces. I don't think it would happen (though I enjoyed the Anglo-Dutch Empire timeline), especially given how badly the Dutch had done under the Anglo-Dutch alliance since the Glorious Revolution.
How long does William III live minus his accident in 1702? What happens differently in the War of Spanish Succession? How long does Mary II live, post-smallpox? Does the kid take over England? Is the Act of Union carried out without a Princess Ann to push it through?
What are the larger effects of the House of Orange ruling England: The American Revolutionary War? The various wars with France? The colonial competition?
Any help is appreciated.
I'm working on a more even industrial race (Dutch-British-French) and was initially going with rather different Napoleonic Wars, but have somewhat reconsidered and am now thinking about an earlier POD—that of William III having a son, whose possibility of taking over the Netherlands drives the Dutch Republic in a different direction from OTL, and whose existence will alter the French-British rivalry.
