The Seven Years' War, which took place from 1755 to 1763, has sometimes been described as the first true world war, in that conflict took place in almost every continent and on almost all the oceans. Although there were early setbacks, British troops eventually were victorious in every theatre. The war can be said to have started in North America, where it was known as the French and Indian War. The early years saw several British defeats. The British units first despatched to the Continent were untrained in the bush warfare they met. To provide light infantry, several corps such as Rogers' Rangers were raised from the colonists. (A light infantry regiment, the 80th Regiment of Light-Armed Foot, was raised by Colonel Thomas Gage, but subsequently disbanded). During the war, General James Wolfe amalgamated companies from several regiments into an ad hoc unit, the Louisbourg Grenadiers.

It was laid down that even the most senior Provincial officers were subordinate to comparatively junior officers in the British Army. The first concern of the colonists' representatives was the protection of the settlers from raids by Native American war parties, while the British generals often had different strategic priorities. Partly through the naval superiority gained by the Royal Navy, Britain was eventually able to deploy superior strength in North America, winning the decisive Battle of the Plains of Abraham at Quebec City and conquering New France. Similarly, in the Indian subcontinent, the French East India Company and the militaries of the most powerful rulers of the Mughal Empire were defeated after the prolonged Third Carnatic War, allowing the steady expansion of British East India Company-controlled territory. In Europe, although Britain's allies (chiefly the Royal Prussian Army) carried the main burden of the struggle, British troops eventually played an important role at the decisive Battle of Minden. Aftermath The result of this war was to leave the British Empire as the dominant imperial power in North America, and the only European power east of the Mississippi River (although it would return East Florida back to the Spanish Empire). There was increasing tension between the British government and the American colonists, especially when it was decided to maintain a standing army in North America after the war. For the first time, the British Army would be garrisoned in North
