Cultural hegemony is the philosophic and sociological theory, by the Marxist philosopher Antonio Gramsci, that a culturally diverse society can be dominated (ruled) by one social class, by manipulating the societal culture (beliefs, explanations, perceptions, values) so that its ruling-class worldview is imposed as the societal norm, which then is perceived as a universally valid ideology and status quo beneficial to all of society, whilst benefiting only the ruling class.
