On 25 September 1555 the imperial Diet at Augsburg proclaimed a religious settlement that ended decades of conflict between Emperor Charles V and the Lutheran princes of the Holy Roman Empire.
Negotiated on the emperor's behalf by his brother Ferdinand, the Peace of Augsburg established the principle later summarised as cuius regio, eius religio, whose realm, his religion, allowing each prince to choose Catholicism or Lutheranism as the official faith of his territory; dissenting subjects were permitted to emigrate. The settlement gave Lutheranism legal recognition within the Empire and marked Charles V's admission that the Habsburg aim of restoring a single Catholic Christendom had failed, contributing to his abdication. Yet the peace recognised only Catholicism and Lutheranism, excluding Calvinism and Anabaptism, an omission that left major confessional tensions unresolved. The unworkable parts of the compromise, alongside the growth of Calvinism, helped set the stage for the catastrophic Thirty Years' War of 1618 to 1648. The Peace of Augsburg nonetheless entrenched religious pluralism as a structural feature of the Empire's constitution.
