I remember from historyclasses that we (talking about Sweden here) quickly converted from Catholicism to Protestantism when Gustav Vasa took power. And after that it was never really brought up again. Except for a brief mention that it might have contributed to the Dacke war, which was mainly talked about as a peasent uprising regarding heavy taxation.
Comparing that to England where catholics tried to blow up the parliament. It really begs the question, to my mind at least, why was it so easy to convert Sweden and Scandinavia? Or was it really so easy?
In Sweden the Dacke war was more about the tyranny of Gustavs rule than a religious turmoil. But Dacke got most of his followers because of the threat that being Lutheran brought. The peasantry was afraid that the being protestant would bring sweden in to a big war, and the confiscation of church property was seen as heresy. When even church bells was taken and made in to cannons the local priests of smaland gave Dacke their support.
Also important to know that the war-torn Sweden was strongly against yet another war, when they had finally gotten out of the kalmar union.
In the 15th-16th century sweden was almost constantly at war against Denmark when the swedish nobility often voted for a non Danish king. So the exhausted sweds accepted the protestants reformation.
Gustav Vasa like every other strong regent in Sweden (Charles IX, Gustavus Adolphus, Charles X, XI and XII) was masters of propaganda. They knew how to manipulate the clergy to speak in their place, and make it seem like it's the will of god. This made disobedience against the king to heresy which was published by death.
Fear of death is mostly why the reformation went so smooth in Sweden. And the small rebellions there were was crushed so brutally that there was no hope for a successful rebellion.
