how does protestant relate to catholic and peace of augsburg

The Protestant Reformation was a religious movement that began in the 16th century in Europe as a response to the Catholic Church. The Peace of Augsburg in 1555 was an agreement between the Holy Roman Emperor and the German princes that allowed each prince to choose either Lutheranism or Catholicism as the official religion of their lands. This agreement ended the religious wars between the two denominations and established a principle of religious tolerance in the Holy Roman Empire.
