- The reform of the Church of Rome in the 16th and 17th centuries which was stimulated by the Protestant Reformation.
Measures to oppose the spread of the Reformation were resolved on at the Council of Trent (1545–63) and the Jesuit order became the spearhead of the Counter-Reformation, both within Europe and abroad. Although most of northern Europe remained Protestant, southern Germany and Poland were brought back to the Roman Catholic Church
