that's a cool timeline, but how did Denmark get the Netherlands?
With Danes-Brittons (Dantons, Branes?) ruling the sea beyond the Dutch coast I guess there is no way around seeking into the Empire for a trading people. If you can't beat them - join 'em!
The starting point point could be a Danish-British supported Dutch rebellion against their Habsburg rulers, and the Dutch being offered a (junior) partnership in the emerging Danish-British(-Hansa) merchant's empire.
Later the French will be a main opponent, and Flanders and Netherlands the gold nuggets over which numerous wars will be fought. By 19th century the Royal Combined Council of Commerce (R3C) and the Habsburg Empire are likely allies against a French-Russian coalition.
In 20th century we will see a global war between the R3C and her allies (Austria, Poland, German Konfederate States, Dacia, Greece, Abyssinia (exile gov.), West African Kingdom, South Africa, China, Siam, Konfederation of India, The Earldoms of Vinland (Canada), Venezuela and Colombia on one side vs. France, Italy, Spain (incl. Portugal), Russia, Serbia, Bulgaria, Japan, Panama, Argentina and Brasil.
A large number of American States initially support the French-Russian alliance, but are beaten into neutrality by a swift campaign early in the war from Vinland and supported by R3C armoured columns and the states preferring to maintain the status quo of political isolation but splendid trading.
