The Seven Years' War lasted from 1756 to 1763. It involved most of the great European powers. At first it was made up of two conflicts. One was mainly between Britain and France. The other was between Prussia and its enemies: France, Austria, Russia and Sweden. Its roots are in an earlier conflict, the War of the Austrian Succession. The war was known by different names in different places. In the United States it is called the French and Indian War. In French Canada it is called the War of the Conquest. In both Sweden and Prussia it was called the Pomeranian War. In India it is known as the Third Carnatic War. When it regards the conflict between Prussia and Austria, it is called the Third Silesian War.
