Feel free to choose or create PODs, but the challenge is: make Canada (or at least a great part of it) and the Northeastern region of US (states of Maine, Vermont, New Hampshire, Massachusets, New York and etc.) territories of strong colonization by Denmark-Norway, Portugal and the Netherlands.
However, there are some conditions for this scenario:
- The POD for Danish-Norwegian and Portuguese colonization must happen
before 18th century. Bonus points if the POD happens during the 16th century, in the apex of the Age of Discovery.
- The POD for Dutch colonization must happen also before 18th century, in a way that prevents further exploration attempts by England and France in those areas.
- Last but not least: all those colonies must somehow
survive to the present day, either as independent countries or overseas departments/provinces.
Some may say it all seems implausible... Well, that's why this kind of thread is called Alternate History Challenge

Good luck
