The most religious parts of Poland are the highlander Podkarpacie region and the Silesia region.

  The most esteemed person for many Poles was John Paul II, the Polish Pope (1920-2005). His popularity is based upon his many pilgrimages and his open attitude towards people, and among the youth he often surpassed the fame of current singers and actors. John Paul II was also known as a supporter of the ecumenical movement, and he played an important role in the fall of communism in Poland.
