Liechtenstein offers protection to adherents of all religions, and considers the "religious interests of the people" a priority of the government. In Liechtenstein's schools, although exceptions are allowed, religious education in Catholicism or Protestantism (either Lutheran or Calvinist, or both) is legally required. Tax exemption is granted by the government to religious organizations. According to the Pew Research Center, social conflict caused by religious hostilities is low in Liechtenstein, and so is government restriction on the practice of religion.
