Imperialism involves extending a country's power and influence through military or diplomatic means. It often involves colonialism, where a country takes control of another, occupies it with settlers, and exploits its resources. Social Darwinism and the concept of the "White Man's Burden" were used to justify imperialism and racism, arguing that white people needed to civilize other cultures. The Scramble for Africa in the late 19th century saw rapid colonization of the continent by European powers through conferences like the Berlin Conference. Colonized peoples often resisted losing their independence and having their way of life changed by colonizers seeking to industrialize and exploit foreign lands for resources.
