The purpose of the counter-reformation was to fight against reformation which was turning more and more people against the Catholic church. The council of Trent was called to host sessions and debate on how the Catholic church should respond to reformation. The Jesuits were important because they started organizing missions worldwide in order to teach people about Catholicism and the pope and Christianity and similar things and were successful at it. The outcomes of the council were a series of declarations on how the church should behave.
