	Until the Reformation, the szlachta were mostly Catholic or Eastern Orthodox ("Pic. 3, 13"). However, many families quickly adopted the Reformed religion. After the Counter-Reformation, when the Catholic Church regained power in Poland, the szlachta became almost exclusively Catholic, despite the fact that Catholicism was not a majority religion (the Catholic and Orthodox churches counted approximately 40% of the population each, while the remaining 20% were Jews and members of various Protestant churches).
