Thirty Years' War (1618-1648)

Overview of the War

  • The Thirty Years' War was a significant conflict in Europe that took place from 1618 to 1648.

Key Themes and Events

  • Ferdinand II's Policies

    • Ferdinand II forced citizens of the Holy Roman Empire (HRE) to adhere to Roman Catholicism.

    • The principle of "whose realm, his religion" allowed the princes of states within the HRE to adopt either Lutheranism, Calvinism, or Catholicism within their respective domains.

    • This policy highlighted the fragmented nature of the Holy Roman Empire, which essentially consisted of a collection of semi-autonomous states with limited authority held by the emperor from the House of Habsburg.
