Answer:nter-Reformation, also called Catholic Reformation or Catholic Revival, in the history of Christianity, the Roman Catholic efforts directed in the 16th and early 17th centuries both against the Protestant Reformation and toward internal renewal. The Roman Catholic Church responded to the Protestant challenge by purging itself of the abuses and ambiguities that had opened the way to revolt and then embarked upon recovery of the schismatic branches of Western Christianity with mixed success. The Counter-Reformation took place during roughly the same period as the Protestant Reformation, actually (according to some sources) beginning shortly before Martin Luther’s act of nailing the Ninety-five Theses to the door of Castle Church in 1517.
