is associated with evolutionary theory but now widely regarded as unwarranted. Social Darwinism was later expanded by others into ideas about "survival of the fittest" in commerce and human societies as a whole, and led to claims that social inequality, sexism, racism and imperialism were justified. However, these ideas contradict Darwin's own views, and contemporary scientists and philosophers consider these ideas to be neither mandated by evolutionary theory nor supported by data. Social Darwinism is further linked with nationalism and imperialism. During the age of New Imperialism, the concepts of evolution justified the exploitation of "lesser breeds without the law" by "superior races." To elitists, strong nations were composed of white people who were successful at expanding their empires, and as such, these strong nations would survive in the struggle for dominance. With this attitude, Europeans, except for Christian missionaries, seldom adopted the customs and languages of local people under their empires. Christian missionaries, on the other hand, were the very first individuals to meet new peoples and develop writing systems for local inhabitants' languages that lacked one. Being critics of Social Darwinism, they ardently opposed slavery and provided an education and religious instruction to the new peoples they interacted with since they felt that this was their duty as Christians.
