This study aims at analyzing the English School perspective on the non-state actors of international relations. In this regard, the study represents an overview of the world society conceptualization of the English School and highlights strengths and limitations of the existing accounts of the concept. The existing literature on the subject mainly concentrates on modern, value-based and global forms of non-state actors in international relations. This study offers an alternative view by emphasizing the importance of including non-global, interestbased and pre-modern non-state actors into the analysis in order to widen the scope of the English School theory. It is argued that the revised version of the world society conceptualization would also contribute to the understanding of modern non-state elements by achieving theoretical generalizations about the non-state dimension of the international relations.
