The Peace of Westphalia (1648) addressed religious conflict within the Holy Roman Empire by establishing a framework for legal pluralism and formalizing the rights of religious minorities.12

Key measures included:

  • Expansion of Toleration: The treaty confirmed the Peace of Augsburg (1555), which had previously granted rights to Lutherans, and extended these protections to the Calvinist church. This secured legal recognition for the three major religious communities: Roman Catholic, Lutheran, and Calvinist.1
  • Standard Year: To resolve disputes over church property, the treaty established 1624 as the "standard year," fixing the religious status of territories based on their possession at that time.1
  • Individual Rights: Within the limits of these confessions, member states were required to allow private worship, liberty of conscience, and the right of emigration for religious minorities and dissidents.1
  • Limiting Intervention: By declaring that protests against the settlement were null and void, the treaty curtailed the influence of the Roman Curia in German internal affairs.1

While these measures fostered stability, they did not apply to non-Catholics within the hereditary lands of the House of Habsburg.1
