British imperialism refers to the expansion of the British Empire from the late 16th century to the early 20th century. This period saw Britain establish colonies and territories across various continents, including North America, India, Africa, and Australia. The British sought to control trade routes, access resources, and spread their culture and political systems. The impact of British imperialism was significant, leading to economic growth for Britain but often resulting in exploitation and oppression in the colonized regions. Indigenous populations faced cultural changes, land dispossession, and social disruption. The legacy of this imperialism continues to influence global relations and post-colonial societies today.
