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. A major impact of the Thirty Years' War was the extensive destruction of entire regions, denuded by the foraging armies. Episodes of famine and disease significantly decreased the populace of the German states, Bohemia, the Low Countries and Italy, while bankrupting most of the combatant powers. Some of the quarrels that provoked the war went unresolved for a much longer time. The Thirty Years' War was ended with the treaties of Osnabrück and Münster, part of the wider Peace of Westphalia.
