This article is based on participant observation within the network “Génération identitaire”. It consists of an ethnographic study of the training camp that has all the characteristics of a full-blown institution. Participants are given role-playing in which they reinvent themselves as the defenders of a territory supposedly threatened from the outside. They see themselves as heroes within a community cut off from the outside world. The closed community in which they operate between their websites and social networks enables them to extend their militant identity. This study shows the impact of this organization in the far-right group’s mobilization on Internet.
