But material "aggrandisement", though the only tangible, was not the only real or lasting effect of a war policy. More could be gained by crushing a formidable rival than by conquering a province.

Such defeats radically affected the future of Europe and the world. Deprived of her most valuable colonies both in the East and in the West, and thoroughly defeated on the continent, France's humiliation was the beginning of a new epoch in history.
