The period in which the Catholic Church responded the Protestant Reformation is known as the Counter-Reformation. There were different ways, in which the Catholic Church responded to the Protestant Reformation. Some of these ways were violent in nature such as the Thirty Years War. Other actions involved a mission to move the parts of the world that had been conquered as Catholic and work to reconvert states including England and Sweden that remained Catholic but Protestantized at the time of the Reformation movement.
