Imperialism is a policy or practice of extending a country's power and influence through colonization, use of military force, or other means of control over other territories or nations. It often involves the exploitation of resources and peoples in the colonized lands for the benefit of the imperial power. Imperialism was a major force in the 19th and early 20th centuries as European powers sought to expand their empires and exert their dominance over other parts of the world.
