Multi-Positioned Actors and the Construction of the Transnational: The Creation of the European Consortium for Political Research Given the very diverse ways in which political science has been structured at the national level and the lack of interaction among national fields, the creation of the European Consortium for Political Research (ECPR) in 1970 was on the face of it improbable. This article explains the genesis of this transnational scholarly organization by reference to two phases: first, by creating the International Political Science Association (IPSA), UNESCO encouraged growth in the transnational circulation of actors and knowledge involved in the study of politics; this circulation subsequently contributed to transforming the physiognomy of European national fields and created the conditions of emergence of a subversive project for a new scholarly organization. The present article thus reveals the hybrid structure of transnational spaces in terms of the knowledge and resources that are involved.
