The Thirty Years' War, fought primarily in Central Europe between 1618 and 1648, was one of the most destructive conflicts in European history. An estimated 4.5 to 8 million soldiers and civilians died from the effects of battle, famine, or disease, with parts of Germany reporting population declines of more than 50%. Related conflicts include the Eighty Years' War, the War of the Mantuan Succession, the Franco–Spanish War, the Torstenson War, and Portuguese Restoration War.
