It is my understanding that during the 30 Years' War (especially when they first joined), Sweden was seen as liberators and champions of the Protestant cause.
Did this favorable view persist in the Swedish holdings in northern Germany after the Peace of Westphalia? Or were the people resentful of the foreign rule?
Was there a noteworthy difference between Catholics and Protestants?
I realize that it's hard to know the opinion of people, but I think it can be gauged by either efforts to integrate more with Sweden, or efforts to gain independence from Sweden.
Were there any notable efforts in either way? If so, were these by nobles trying to increase their own power, or were they popular in nature?
