 This approach might be called "actor-centered history": we explain a historical moment or event when we have an account of what people thought and believed; what they wanted; and what social, institutional, and environmental conditions framed their choices. It is a view of history that gives close attention to states of knowledge, ideology, and agency, as well as institutions, organizations, and structures, and examines the actions and practices of individuals as they lived their lives within these constraining and enabling circumstances. Further, it emphasizes the contingency and path-dependency of history, and it acknowledges the fact of heterogeneity of institutions, beliefs, and actions across time and place.
