7.4 Darwinism and Social Darwinism

TLDR

Charles Darwin's theory of natural selection, published in On the Origin of Species (1859), gave a scientific and material explanation for how species change over time. Thinkers later twisted his ideas into Social Darwinism, which falsely claimed some races, nations, and classes were naturally superior, and that claim was used to justify racism and imperialism. For AP European History, you need to explain how Darwin's science influenced both intellectual life and the racialist thinking of the late 19th century.

Why This Matters for the AP European History Exam

This topic sits inside a larger shift after the revolutions of 1848, when Europe moved toward a realist and materialist worldview. Darwin's work is a clear example of that materialist turn, since it explained human origins through natural processes instead of only religious or philosophical accounts.

You will likely see Darwinism and Social Darwinism in causation and continuity/change reasoning. The key move is distinguishing Darwin's actual scientific claims from how others applied (and misapplied) them. Social Darwinism also connects directly to the cultural and racial justifications for New Imperialism in later topics, so this concept gives you usable evidence for arguments about why Europeans expanded overseas and how they defended that expansion.

Key Takeaways

• Darwin gave a scientific, material account of biological change and human development as a species, mainly in On the Origin of Species (1859) and The Descent of Man (1871).
• Natural selection means individuals with traits better suited to their environment are more likely to survive and reproduce, so those traits spread over generations.
• Social Darwinism was an unintended outgrowth of Darwin's work, not part of his original theory.
• Social Darwinism applied "survival of the fittest" to human society to claim some races, nations, and classes were naturally superior.
• These racialist ideas were used to justify imperialism, colonial exploitation, and discrimination as part of a supposed natural order.
• Darwin's ideas fit the broader post-1848 realist and materialist worldview in European thought.

Darwinism: The Theory of Natural Selection

Charles Darwin was an English naturalist whose work changed how Europeans understood life itself. After observations made during his voyages, including time near the Galapagos Islands, he developed the theory of natural selection, published in On the Origin of Species in 1859.

His core ideas:

• Natural selection: Individuals with traits that fit their environment better are more likely to survive and reproduce. Over many generations, those helpful traits become more common in a population.
• Survival of the fittest: A phrase tied to Darwin's theory describing how better-adapted individuals survive and pass on their advantageous traits. (Darwin did not originally coin this phrase, but it became attached to his ideas.)
• Evolution: Over long stretches of time, the buildup of beneficial traits produces evolutionary change in species.

What makes Darwin so important for this period is that he provided a scientific and material explanation for biological change and for the development of human beings as a species. That fits the larger trend after 1848, when European thought leaned toward realism and materialism, trusting scientific and rational explanations of nature and human affairs.

Darwin's natural selection was a biological theory. It was not designed to explain how human societies should be organized. That distinction matters, because the social application came from other thinkers.

Social Darwinism: Applying Evolution to Human Society

Darwin's later work, The Descent of Man (1871), extended his theory to human origins and looked at human development as a species. Other writers stretched these ideas far beyond biology and used them to explain social, political, and economic inequality.

Social Darwinism took the language of "survival of the fittest" and applied it to human societies. It claimed that certain races, nations, and classes were naturally superior to others, and that social and economic inequalities simply reflected a natural hierarchy. The important point for the exam: Darwin provided the scientific account, and Social Darwinism was an inadvertent justification for racialist theories built on top of his work.

Impact on Racial Theories and Imperialism

Social Darwinism became a tool for racist and imperialist thinking in the late 19th and early 20th centuries.

• Racial hierarchies: Supporters claimed racial inequality was biologically determined, casting non-European societies as "primitive" or "inferior." This idea has no scientific basis.
• Imperialism and colonialism: The claim that the "fittest" nations had a duty to control and "civilize" others helped justify European expansion in Africa and Asia, and was used to rationalize the exploitation of colonized peoples.

This is why Social Darwinism shows up again when you study New Imperialism. It worked alongside ideas like "The White Man's Burden" and the French mission civilisatrice as a cultural and racial justification for overseas rule. Treat those as examples of how the concept was applied, not as separate required theories.

Common Misconceptions

• Darwin invented Social Darwinism. He did not. Darwin's theory was biological, and Social Darwinism was a later misapplication of his ideas to human society.
• Social Darwinism is real science. It is not. The claim that some races are biologically superior has been thoroughly discredited and has no scientific support.
• "Survival of the fittest" was Darwin's original phrase. The phrase became associated with his theory, but it was not the original wording of natural selection, and "fittest" means best suited to an environment, not strongest or best overall.
• Darwin's theory only mattered for science. Its influence reached intellectual, social, and political thought, which is exactly why this topic pairs scientific and social developments together.
• Social Darwinism explains imperialism by itself. It was one justification among several. European expansion also had economic, political, and strategic motivations that you should pair with it in any argument.

How to Use This on the AP European History Exam

Multiple Choice

Expect sources that praise science, progress, or racial "fitness." Identify whether a passage is making a biological claim (Darwinism) or a social and political claim about human hierarchy (Social Darwinism). Watch for documents that use scientific-sounding language to defend imperialism or inequality.

Free Response

Use Darwin as evidence for the post-1848 shift toward a realist and materialist worldview. Use Social Darwinism as evidence in arguments about the cultural and racial motivations behind New Imperialism. Be precise: explain that Darwin gave a scientific account and that others turned it into a justification for racialist theories.

Common Trap

Do not blur Darwin's science with Social Darwinism. The strongest responses show that you understand the gap between Darwin's biological theory and how it was misused to justify racism and empire. Naming that distinction clearly earns credit and avoids inaccurate claims.
