The main theme of this dissertation is to analyse the English School`s project for International Relations, one of the key attempts to historicize IR theory. First of all, the work examines the English project and its contradictory proposal based on natural rights` principles and the attempt to bring history into the discipline. Although the analysis usually repeat this paradox, it is possible to consider the concept of international society as a valuable starting point to unite history and IR theory. The study, then, turns towards the investigation of the historical ontology developed by Hegel, especially his theory of recognition. Once the major points of the Hegelian perspective are made clear, some questions about his political philosophy are examined. Finally, it will be argued that through the Hegelian concept of recognition, which is based on Hegel`s own idea of historicity, it is possible to avoid the usual natural right`s principle associated to the original concept of international society. By adding recognition to the concept of international society, its content is provided with dynamism and therefore, it becomes capable of avoiding the traditional ahistoricism of IR theories.
