The Counter-Reformation in Poland (Polish: Kontrreformacja w Polsce) was the response (Counter-Reformation) of Catholic Church in Poland (more precisely, the Kingdom of Poland until 1568, and thereafter the Polish–Lithuanian Commonwealth) to the spread of Protestantism in Poland (the Protestant Reformation). Counter-Reformation in Poland lasted from the mid-16th century until the mid-18th century and ended with the victory of the Catholic Church, which succeeded in significantly reducing the influence of Protestantism in Poland.
