As with any other social event, festivities can be studied by relational sociologists, who can trace out the web of links that brings the crowd to the streets and makes festival-goers enjoy their stay. In this chapter, I examine three approaches to the relational study of festivities. The first one is the network analysis; the second is the “Bourdieusian,” in which distinctive behaviors prevent the possibility that the entire population can enjoy a single event. Finally, there is a “Latourian” approach that focuses on the formation of effervescent gatherings, notably thanks to material devices, without taking into proper consideration the outcome of the festivity. The second part is grounded on the ethnography of the relations necessary to create a festivity in the Durkeimian approach. These relations are mainly used to create groups of festival-goers, either small groups or large ones, based on kin, friends, work relations, or gender relations. Then, during the festivities, these groups establish relations based on unplanned encounters with fellow festival-goers that increase their enjoyment of the festivity.
