Anglo-Prussian Alliance (1756)

Frederick the Great, King of Prussia during the alliance. He was the nephew of George II and first cousin once removed of George III, the respective sovereigns of Great Britain and Hanover.

The Anglo-Prussian Alliance was a military alliance created by the Westminster Convention between Great Britain and Prussia that lasted formally between 1756 and 1762, during the Seven Years' War. The alliance allowed Britain to concentrate most of its efforts against the colonial possessions of the French-led coalition while Prussia bore the brunt of the fighting in Europe. The alliance ended in the final months of the conflict, but strong ties remained between both kingdoms.
