I want to know the answer to the following question:
How much was the German population reduced during the Thirty Years' War?
All the background I'm provided with is that "After the Eighty Years' War in the Low Countries and the French Wars of Religion, the confessional division of the states of the Holy Roman Empire eventually erupted in the Thirty Years' War between 1618 and 1648.". Is that enough to answer the question?
Answer: no
