Definition of counter reformation??

The Counter-Reformation was a period of Catholic resurgence in response to the Protestant Reformation. It was a movement within the Catholic Church to reform itself and combat the spread of Protestantism. The Counter-Reformation involved efforts to clarify and strengthen Catholic doctrine, address corruption and abuses within the Church, and promote Catholic education and missionary work. It also included the establishment of new religious orders, such as the Jesuits, to help spread Catholicism and combat heresy. The Council of Trent, held from 1545 to 1563, was a key event in the Counter-Reformation, as it addressed many of the issues raised by the Protestant Reformers and reaffirmed Catholic teachings.
