How is Social Darwinism and White Mans Burden used to justify Imperialism?

Social Darwinism and the notion of the "White Man's Burden" were used to justify Imperialism by framing it as a moral obligation of Western powers to civilize and uplift "lesser" societies. Social Darwinism applied the concept of "survival of the fittest" to nations, suggesting that imperialism was a natural and beneficial process for both the colonizers and the colonized. Meanwhile, the "White Man's Burden" posited that it was the duty of Europeans to educate and govern non-Western peoples, often disregarding their cultures and autonomy. Together, these ideologies provided a veneer of legitimacy for the exploitation and domination inherent in imperialist practices.
