The correct answers are 1.- Imperialism. 2.- European.
Social Darwinism helped to justify IMPERIALISM by suggesting that it is natural and acceptable for powerful, and wealthy nations to colonize regions that are less powerful. EUROPEAN nations used this theory to justify the practice of political, economic, and cultural colonialism.
Under the concept of "survival of the fittest," Social Darwinism was a concept created in the late 1800s that believed that some people were born strong enough to dominate the others, and this idea was applied to society and nations. From then on, Social Darwinism has been used by dictators, Tyrans, and powerful people to adopt racist practices, invasions, and imperialism.
