On the international stage, Britain emerged as a dominant global power. The century was defined by imperial expansion, with the British Empire stretching across the Americas, India, Africa, and the Pacific. Foreign policy was marked by both war and diplomacy, notably in the Seven Years' War (1756–1763), which solidified British supremacy over European rivals such as France and Spain. Meanwhile, tensions with American colonies would eventually lead to the American Revolution, a significant turning point in British foreign relations and colonial policy.
