Critical Theory refers to the body of social and cultural analysis developed by the Frankfurt School — the Institute for Social Research, founded in Frankfurt in 1923 and later relocated to New York after the Nazi seizure of power. Its key figures include Max Horkheimer, Theodor Adorno, Herbert Marcuse, Walter Benjamin, and, in a later generation, Jürgen Habermas.

What it argued

Critical Theory was a response to a central puzzle: why had the European working class not made a revolution, despite the conditions Marx had identified as sufficient to produce one? The Frankfurt School’s answer focused on culture, mass media, and the structure of rationality itself. In Dialectic of Enlightenment (1944), Horkheimer and Adorno argued that Enlightenment reason, intended as a tool of human liberation, had become a tool of domination — in the form of Nazi totalitarianism, Stalinist bureaucracy, and the American culture industry. The culture industry — Hollywood, popular music, advertising — manufactured false needs and passive consumers who could not imagine alternatives to the existing order.

How to use it in an answer

Critical Theory is most relevant to questions about the Frankfurt School’s ideas directly, or to broader questions about the relationship between culture, ideology, and political power. Adorno’s analysis of the culture industry, and Benjamin’s essay on the work of art in the age of mechanical reproduction, are the most frequently encountered Frankfurt School texts at A-level. Understanding what these arguments are actually claiming — rather than just naming the school — is what earns marks.
