During the 19th century, European imperialism expanded significantly as major powers sought to control weaker nations in Africa, Asia, and elsewhere for economic and political gain. Motivations included acquiring raw materials, spreading social ideologies like Social Darwinism and Christianity, and enhancing national prestige. Countries like Britain, France, Portugal, the Netherlands and others established colonies, protectorates and spheres of influence through more advanced military technology and imposed direct or indirect rule over local populations. This period led to extensive European control over much of Asia and Africa.
