3.8 Effects of Seventeenth-Century Crises

Population, War, and Religious Conflict

The 17th century saw recurring famine, plague, and warfare, especially the devastating Thirty Years' War (1618–1648), which killed roughly a third of Germany's population. Religious tensions between Catholics and Protestants fueled conflict until the Peace of Westphalia (1648) ended the war, affirming state sovereignty and the principle that rulers chose their state's religion.

The 'General Crisis' and Its Consequences

Historians describe this era as a General Crisis, marked by economic stagnation, climate cooling (Little Ice Age), and widespread revolts against rising taxes and centralizing monarchs (e.g., the Fronde in France, English Civil War). These crises pushed states toward stronger central authority to restore order, accelerating the rise of absolutism in places like France.

New Political and Economic Order

Westphalia established the modern state sovereignty system, reducing the Holy Roman Empire's power and weakening the papacy's political influence. Governments increasingly turned to mercantilist policies and larger standing armies to secure resources and stability, reshaping the balance of power among European states for centuries.
