By 1756 the wilderness war for control of North America that erupted two years earlier between France and England had expanded into a global struggle among all of Europe's Great Powers. Its land and sea battles raged across the North American continent, engulfed Europe and India, and stretched from the Atlantic to the Mediterranean, Indian, and Pacific waters. The new conflict, now commonly known as the Seven Years' War of 1756-1763, was a direct continuation of the last French and Indian War. This study explores the North American campaigns in relation to events elsewhere in the world, from the ministries of Whitehall and Versailles to the land and sea battles in Europe, Africa, South Asia, and the Caribbean.

Few wars have had a more decisive effect on international relations and national development. The French and Indian War resulted in France's expulsion from almost all of the Western Hemisphere, except for some tiny islands in the Caribbean and St. Lawrence. Britain emerged as the world's dominant sea power and would remain so for two centuries. Finally, within a generation or two the vast debts incurred by Whitehall and Versailles in waging this war would help to stimulate revolutions in America and France that would forever change world history.
