One way the Catholic Church tried to stop the spread of Protestantism was through the establishment of the Council of Trent in 1545. The Council aimed to address the issues raised by the Protestant Reformation and reaffirm Catholic doctrine, as well as to implement reforms within the Church. Another method used was the establishment of the Roman Inquisition in 1542, which sought to root out heresy and punish those who spread Protestant ideas. These efforts helped the Catholic Church to maintain its influence and counteract the growing popularity of Protestantism in Europe.
