The Counter-Reformation (Latin: Contrareformatio), also called the Catholic Reformation (Latin: Reformatio Catholica) or the Catholic Revival, was the period of Catholic resurgence that was initiated in response to the Protestant Reformation. It began with the Council of Trent (1545–1563) and largely ended with the conclusion of the European wars of religion in 1648. Initiated to preserve the power, influence and material wealth enjoyed by the Catholic Church and to present a theological and material challenge to Reformation, the Counter-Reformation was a comprehensive effort composed of apologetic and polemical documents, ecclesiastical reconfiguration as decreed by the Council of Trent, a series of wars, and political maneuvering. The last of these included the efforts of Imperial Diets of the Holy Roman Empire, exiling of Protestant populations, confiscation of Protestant children for institutionalized Catholic upbringing, heresy trials and the Inquisition, anti-corruption efforts, spiritual movements, and the founding of new religious orders. Such policies had long-lasting effects in European history with exiles of Protestants continuing until the 1781 Patent of Toleration, although smaller expulsions took place in the 19th century.
