The British Colonial Wars were a series of military conflicts that occurred during the expansion of the British Empire from the 17th to the 20th centuries. These wars often involved battles against indigenous peoples, rival European powers, and other colonial forces. Key conflicts included the Seven Years' War, the Anglo-Zulu War, and the First and Second Opium Wars. These wars were driven by the desire for territorial expansion, control of trade routes, and access to resources. The outcomes often resulted in significant changes in political boundaries and the establishment of British dominance in various regions, including parts of North America, Africa, and Asia.
