Social Darwinism, imperialism, and Anglo-Saxon superiority

Explanation:

This is what the expansionist foreign policy of the 1890s derived significant inspiration from. During these years, many countries engaged in projects of imperialism and expansion. These were often driven by the belief that white people had a responsibility towards other countries and peoples of bringing civilization and advancement to those who did not enjoy it. It was also underpinned by a belief in the evolutionary superiority of the Anglo-Saxon race.
