The British Empire expanded greatly during the Victorian era in the 19th century. New colonies were established in Africa, Asia, the Pacific, and Australia to replace territories lost in North America. The British justified this imperial expansion by claiming their culture and religion were superior and needed to be spread for the benefit of indigenous peoples. In reality, the main motivations were economic, with colonies providing raw materials and new markets that strengthened British industry and trade. While the Empire enriched Britain, controlling vast territories was also very costly and damaged local cultures.
