What is the Thirty Years' War?

The Thirty Years' War (1618-1648) was fought primarily in what is now Germany, and at various points involved most countries in Europe. It was one of the most destructive conflicts in European history.

The origins of the conflict and goals of the participants were complex, and no single cause can accurately be described as the main reason for the fighting. Initially, the war was fought largely as a religious conflict between Protestants and Catholics in the Holy Roman Empire, although disputes over the internal politics and balance of power within the Empire played a significant part. Gradually, the war developed into a more general conflict involving most of the European powers. In this general phase, the war became more a continuation of the Bourbon-Habsburg rivalry for European political pre-eminence, and in turn led to further warfare between France and the Habsburg powers, and less specifically about religion.
