Answer:
During the process of Reformation and Counter Reformation, there were constant political turbulences in Europe that led to conflicts. During that period certain countries allowed the spreading of Protestantism, but some did not. That was the case of Spain, where Philip II ruled as a Catholic king, implementing the church laws in everyday life and not allowing the spreading of Heresy. This made him one of the most powerful rulers of 16th Century.
Step-by-step explanation:
Philip II ruled a vast land that included many colonial lands, but also Dutch provinces. He strongly objected the spreading of Protestantism and would even send his cardinals to deal with political matters. His absolutistic reign was repressive and was consider as a man who didn't allow mistakes to be made.
