British expeditions refer to various journeys undertaken by explorers from Britain, primarily during the 18th and 19th centuries. These expeditions aimed to discover new lands, map uncharted territories, and expand knowledge about different cultures and natural resources. Notable expeditions include those led by James Cook, who explored the Pacific Ocean, and David Livingstone, who ventured into Africa. Many British expeditions were sponsored by the government or scientific societies, contributing to advancements in geography, biology, and anthropology. They often resulted in the establishment of trade routes and colonies, significantly impacting global history and the British Empire's expansion.
