What Is the Main Religion in Poland?

The main religion in Poland is Catholicism, as approximately 95 percent of the population is Catholic. There are four branches of Catholicism in Poland: Byzantine-Ukrainian, Neo-Uniate, Armenian and Roman Catholic. Roman Catholics are the largest, numbering over 25 million.

In 1996, Pope John Paul II reformed the territorial division of the Church of Poland. This bull created 40 dioceses and 13 Latin metropolitan archdioceses, and it also created one Byzantine-Ukrainian metropolitan archdiocese. Each diocese is headed up by a bishop, and all of the bishops together form the Episcopate of Poland.

There are several other prominent religious organizations in Poland, such as Orthodox Christianity and Protestantism.
