​​​​This seminal article is one of the founding texts of Critical Theory in International Relations. In this article, Robert Cox advances a critical alternative to traditional International Relations theory by foregrounding the dialectical relationship between social forces, forms of state, and structures of world order, rather than limiting analysis to interactions among states as isolated units. Cox further distinguishes between problem-solving theory, which takes the existing order as a given and seeks to preserve and improve its functioning, and critical theory, which questions the historical conditions that produced that order, exposes its underlying power relations, and illuminates the possibilities for its transformation. He develops the concept of historical structures as continually evolving configurations composed of material capabilities, ideas, and institutions, and reconceptualizes hegemony as a congruence between power, ideology, and institutions, rather than as the mere material preponderance of a single state.​​​
