In North America, the Seven Years' War (1756–1763) was known as the French-and-Indian War (1754–1763). The war in North America was a continuation of a long conflict between Britain and France for supremacy in that continent. When the decisive French-and-Indian War ended, Britain became the dominant power, as France was ejected from the continent.
The decisiveness of the British victory led to friction between London and its thirteen American colonies. The colonists no longer needed British protection or support. The relationship deteriorated badly during the dozen years between the French-and-Indian War and the American Revolutionary War (1775–1783).
Britain's victory over France had been expensive, and London expected the American colonies to repay the costs. Therefore, London implemented a series of measures to collect taxes from the Americans. These taxes were bitterly resented by the colonists.
The end of the French-and-Indian War led to the end of the policy of salutary neglect, which had allowed the colonists to enjoy a great amount of autonomy. After 1763, the British sought much greater control over colonial affairs. This control was not limited to taxation of the colonists; for example, the British ordered the colonists not to settle beyond the Appalachians.
The growing tensions between London and its thirteen colonies led to the outbreak of the American Revolution.
