Social Darwinism, the theory that persons, groups, and races are subject to the same laws of natural selection as Charles Darwin had perceived in plants and animals in nature.
Social Darwinism was a sociological theory popular in late nineteenth-century Europe and the United States. It merged Charles Darwin's theory of natural selection and Herbert Spencer's sociological theories to justify imperialism, racism, and laissez-faire (i.e. conservative) social and economic policies.
