British Imperialism refers to the period when the British Empire expanded its control over vast territories around the world, particularly from the late 16th century to the early 20th century. This expansion was driven by the desire for new markets, resources, and strategic advantages. Countries in Africa, Asia, and the Americas were colonized, leading to significant cultural, economic, and political changes in these regions. During this time, the British established colonies, protectorates, and dominions, often justifying their actions with the belief in their superiority and the idea of the "civilizing mission." The impact of British Imperialism is still felt today, as many former colonies continue to navigate the legacies of colonial rule and strive for independence and self-determination.
