Summary
DescriptionThe Counterreformation.svg
English: In 1545, the Council of Trent officially launched the Counter-Reformation against Protestantism in Europe to restore unity in the Catholic Church. This effort concluded in 1648, as did the Protestant Reformation itself.
Additional note: This map could be more detailed but it is not for good reasons. Arminianism, Baptists, Quakers and some other English dissenters that deviate much from Calvinism are excluded due to either problems with recognition (i.e. Arminianism is claimed by some to be only a soteriological diversification of Calvinism) or complicated distribution. Also, I decided to keep it the way it is to keep only the basic and necessary information and to avoid overdetail.
