Cultural materialism is an anthropological school of thought that examines material conditions like climate, food supply, and geography to understand human culture. It views these material factors as the primary determinants of cultural differences and similarities between societies. Cultural materialism also describes a politicized form of historiography that studies historical materials within a politicized framework, including how literary texts have helped shape the present. The term was coined in 1985 by Jonathan Dollimore and Alan Sinfield to describe a critical method with four key aspects: a theoretical method, political commitment, textual analysis, and the view that culture cannot transcend material forces and modes of production.
