Seven Years' War: The Battle of Minden, an allied Anglo-German army victory over the French. In Britain this was one of a number of events that constituted the Annus Mirabilis of 1759 and is celebrated as Minden Day by certain British Army regiments.

The Seven Years' War, 1756 to 1763, was a Great Power conflict fought primarily in Europe, with significant subsidiary campaigns in North America and South Asia. The warring states were Great Britain and Prussia fighting against France and Austria, the respective coalitions receiving assistance from countries including Portugal, Spain, Saxony, Sweden, and Russia. Related conflicts include the Third Silesian War, French and Indian War, Third Carnatic War, Anglo-Spanish War (1762–1763), and Spanish–Portuguese War.

The Battle of Minden was a major engagement during the Seven Years' War, fought on 1 August 1759. An Anglo-German army under the overall command of Prussian Field Marshal Ferdinand of Brunswick defeated a French army commanded by Marshal of France, Marquis de Contades. Two years previously, the French had launched a successful invasion of Hanover and attempted to impose an unpopular treaty of peace upon the allied nations of Britain, Hanover and Prussia. After a Prussian victory at Rossbach, and under pressure from Frederick the Great and William Pitt, King George II disavowed the treaty. In 1758, the allies launched a counter-offensive against the French and Saxon forces and drove them back across the Rhine.

Great Britain was one of the major participants in the Seven Years' War, which for Britain in fact lasted nine years, between 1754 and 1763. British involvement in the conflict began in 1754 in what became known as the French and Indian War. However the warfare in the European theatre involving countries other than Britain and France commenced in 1756. Britain emerged from the war as the world's leading colonial power, having gained all of New France in North America, ending France's role as a colonial power there. Following Spain's entry in the war in alliance with France in the third Family Compact, Britain captured the major Spanish ports of Havana, Cuba and Manila, in the Philippines in 1762, and agreed to return them in exchange for Spanish Florida. The Treaty of Paris in 1763 formally ended the conflict and Britain established itself as the world's pre-eminent naval power.
