The Frankfurt School is a school of thought in sociology and critical philosophy. It is associated with the Institute for Social Research founded at Goethe University Frankfurt in 1923. Formed during the Weimar Republic during the European interwar period, the first generation of the Frankfurt School was composed of intellectuals, academics, and political dissidents dissatisfied with the contemporary socio-economic systems of the 1930s; namely, capitalism, fascism, and communism. The Frankfurt theorists proposed that existing social theory was unable to explain the turbulent political factionalism and reactionary politics, such as Nazism, of 20th-century liberal capitalist societies. Also critical of Marxism–Leninism as a philosophically inflexible system of social organization, the School's critical-theory research sought alternative paths to social development. What unites the disparate members of the School is a shared commitment to the project of human emancipation, theoretically pursued by an attempted synthesis of the Marxist tradition, psychoanalysis, and empirical sociological research.
