Résumé
The introduction to this special issue aims to provide an analysis of several case studies related to international security issues using the concept of politicisation. Beginning with a brief review of the literature on the use of this concept by international relations scholars over the past two decades, the paper then identifies the limitations of the current state of the art. Our contribution thus presents the contributions of the case studies proposed in this special issue and suggests that the politicisation of security issues should be considered not so much as a mechanical process, but rather as a set of practices produced by political or social actors at the national and/or international level. From this perspective, this introduction builds on the work of political sociology and the political sociology of public action, and thus aims to foster a dialogue between security studies and this literature.
