The Counter-Reformation (also known as the Catholic Reformation), which dates from 1560 to 1648, was the Catholic Church's response to the Protestant Reformation in the 16th century. The Counter-Reformation served as a strong and rather conservative reaction to Protestantism. The Counter-Reformation served, in many respects, as the Catholic Church's response to Martin Luther. The Counter-Reformation, in many respects, led directly to the birth of the modern Catholic Church. The reforms of the Counter-Reformation led to the end of the selling indulgences, better education for priests, reformulated church laws, and the establishment standardized worship services.
catolics were the people who continued their loyality to the pope. when the protests reformation broke out the catolics became aware of the evils inside the church. so they try to purify the church by clearing out the evils in the churches. this is called the catolic reformation.
