Nordic great power and the early history of North America

[True Federalist (진정한 연방 주의자)]

A revived Kalmar Union would have been severely playing above its weight class.  It simply did not have the manpower or the economy to sustain what it was doing.

Leaving aside the St. Petersburg area would not have developed as it did if it remained in Swedish hands, a union of all the Scandanavian countries plus the entire Baltic littoral (including parts Sweden never held) if done today would gave population of only a little over 40 million people.  (See below)

By necessity, it would need to devote considerable resources to defend the Baltic littoral from Russia, Poland, and the Holy Roman Empire.  Resouces that England did not have to devote itself to, and thus was able to use in other ways.

A Second Kalmar Union would have had neither the resources nor the inclination to be involved in thwarting British colonial efforts to any large degree, unless...

If the throne of Scotland had become united with the Scandanavian thrones in an unbroken First Kalmar Union, then you can begin to speak of a great Northern superstate that would have a reasonable chance of disputing English dominance of the seas.
