The Seven Years' War.

Explanation:

The Seven Years’ War contained the conflict between Britain and its Bourbon adversaries, France and Spain, as well as the dispute between Frederick II of Prussia and his enemies: Austria, France, Russia, and Sweden.

While the Treaty of Paris (1763) between Great Britain, Hanover, France, and Spain established the colonial power of Britain, the Treaty of Hubertusburg, between Austria, Prussia, and Saxony, allowed Prussia to emerge as a vast power that could no longer be questioned.
