British West Africa was a region in West Africa that was under British colonial rule during the late 19th and early 20th centuries. It primarily included territories such as Ghana, Nigeria, Sierra Leone, and The Gambia. The British established control over these areas for economic exploitation, trade, and to spread their influence. The region was characterized by diverse cultures, languages, and economies. The British implemented various administrative systems, which often disrupted local governance. The legacy of British colonialism in British West Africa continues to influence the political and social landscapes of these countries today.
