Seven Years’ War, (1756–63), the last major conflict before the French Revolution to involve all the great powers of Europe. Generally, France, Austria, Saxony, Sweden, and Russia were aligned on one side against Prussia, Hanover, and Great Britain on the other. The war arose out of the attempt of the Austrian Habsburgs to win back the rich province of Silesia, which had been wrested from them by Frederick II (the Great) of Prussia during the War of the Austrian Succession (1740–48). But the Seven Years’ War also involved overseas colonial struggles between Great Britain and France, the main points of contention between those two traditional rivals being the struggle for control of North America (the French and Indian War; 1754–63) and India. With that in mind, the Seven Years’ War can also be seen as the European phase of a worldwide nine years’ war fought between France and Great Britain. Britain’s alliance with Prussia was undertaken partly in order to protect electoral Hanover, the British ruling dynasty’s Continental possession, from the threat of a French takeover.
hopefully this helped, sorry if it doesn't.
