why was the protestant reformation successful?Watch
I'm going to quote in Tank Girl now so she can move your thread to the right place if it's needed.
Politically it was about less hierarchy and one based on national churches not giving money to rich foreigners. The sharp elbowed ascendant powers of the time all went Protestant presumably because they felt they were the ones paying for everyone else?
It was successful because the people who put the Bible above the Church were willing murder Catholics and keep doing so. I often say Protestantism is the most violent religion on earth because it is. Protestantism was forged on this willingness to commit immoral acts of violence to maintain the faith and the power which was gained with the break from Rome. In the end it was a stalemate and the Catholics couldn't have a military victory against people will to do the same to them. Of course there was a religious aspect people truly believed the holy words of the bible and that the Church went against many things within the Bible because it did. But as I always say in the end people don't matter, institutions do. The reformation was about power within Europe and was successful for that reason.
