The concept of hegemony has regained attention from various theoretical perspectives in International Relations. This article argues that IR-poststructuralism can offer an independent perspective on the production of hegemonies in international politics. Based on IR-poststructuralism and poststructuralist discourse theory, it develops a conceptual framework and an associated methodological approach for the analysis of international hegemonies in concrete discourses. Thereby, the article conceptualises international hegemonies as the creation of a specific type of collective identity while arguing that for hegemonies to emerge, both the creation of an antagonistic Other and a vision of the opposed Self are necessary. The workings of the conceptual framework are illustrated with a comparative reconstruction of United Nations discourses on international terrorism and drug prohibition from 1961 to 2011.
