The Peace of Augsburg was a treaty between Charles V and the forces of the Schmalkaldic League, an alliance of Lutheran princes, on September 25, 1555, at the imperial city of Augsburg, now in present-day Bavaria, Germania.
It officially ended the religious struggle between the two groups and made the legal division of Christendom permanent within the Holy Roman Empire. The Peace established the principle Cuius regio, eius religio, which allowed Germanian princes to select either Lutheranism or Catholicism within the domains they controlled, ultimately reaffirming the independence they had over their states. Subjects, citizens, or residents who did not wish to conform to the prince's choice were given a period in which they were free to migrate to different regions in which their desired religion had been accepted.
