The tactics and strategies which Rome has employed over the centuries are:
#5. Insurgence - To counter the Protestant Reformation Rome turned to the use of political and military force. Where natives in new lands in South America or people in European nations needed "convincing" to become Catholic or to return to Catholicism, Catholic rulers such as Phillip II of Spain and later the Holy Roman Emperor, Ferdinand II, used political and even military coercion, either to enforce Catholicism on all in a given area or to force those who wanted to remain Protestant to leave altogether.
Across Europe from 1560-1715 there was the Age of Religious Wars. It is reckoned that between 1560 and 1715, Europe witnessed only thirty years of any semblance of peace. Romanism was being threatened on every hand, not only by the doctrines of Lutheranism but also by those of Calvinism. Biblical truth was spreading even into Catholic nations and Rome was not happy. Her answer was to wage war to the death upon Protestants, in Germany, Bohemia, France, Netherlands, England and Scotland.
