The historical period known as Procés, or the Catalan independence process, has been characterized by an extraordinary political activation that has led to the generation of mass mobilizations. In this process, the individual and collective experimentation of emotions and affections has had a fundamental weight that has not only conditioned political experiences but has created new ones. Ethnographic work has shed light to the idea that the emotion of fear has been widely experienced by supporters of Catalan independence, both on a latent and unspecific level, as a constant threat, but also in specific and localized episodes temporally and spatially. Far from serving to disactivate political activities, fear has activated individual and collective strategies, creating new affective networks, which have made it possible to link the political and mobilizing sphere with the emotional one.
