Seven Years‘ War

Brühl organised a European power alliance against the Kingdom of Prussia. However, Frederick II of Prussia occupied neighbouring Saxony and held his own against all opponents in the Seven Years' War, causing Brühl's long-term foreign policy concept to fail. With the Peace of Hubertusburg in 1763, Saxony left the circle of the great European powers. Had Brühl's coalition won, which was entirely possible and only failed due to coincidences, Prussia would not have risen to become the dominant military power that spread like an oil slick across the map in the 19th century and eventually absorbed all of Germany.
