The Protestant Reformation began in 1517 when Martin Luther issued his 95 Theses criticizing Catholic Church abuses such as the selling of indulgences. Luther's movement sparked a religious revolution in Germany and other states. By 1555, the Peace of Augsburg forced the Holy Roman Empire to allow German states to choose either Catholicism or Lutheranism. Other reform movements like Calvinism and the Church of England also emerged during this period of religious upheaval in Western Europe.
