Resumo. The feast of the "Lord Jesus of Great Power" is the greatest folkloric event of the city of La Paz (Bolivia). The research developed is theoretically anchored in the field of social and cultural practices, more specifically in the theory of folk communication. Therefore, the objective of this work is to carry out a folk communicational and folkmedia analysis of this festival, simultaneously considered as a festival, investigating in what ways it acts to promote the communication of the marginalized and folklore as a democratizing socio-cultural practice. The approach adopted is qualitative, the methodology starts from the bibliographic survey and subsequent theoretical and documental analysis of a series of research linked to the folk communicational field, the main tools used are the observation and photographic record of practices, festive rituals and, in a special way, the dances presented in its course. However, it was also used semi-structured interviews with some characters active in the party. The reflective challenge of this text points to the inclusion of the theory of folk communication, in the Bolivian academic field, since, at least until this moment and by the surveys carried out, this discussion has been absent. So it also resembles as a result, the addition of other theoretical categories such as: social and cultural practices and cultural resistance, in this context. The research is justified, to the extent that it opens a horizon of visibility, regarding the importance of the analysis of this folkloric event, as well as the issues related to communication of the marginalized in Bolivia.
