The ritual life of the Kaingang, an Amerindian society of Brazil, is characterized by the celebration of a second funeral rite, named Kikikoi, which they explicitly associate with the representation of their Amerindian identity and the claim of their constitutional and territorial rights. As a result of strong external pressures, its realization was suspended for nearly twenty-five years. Its recovery in 1976 gave it a second life that lasted a little more than thirty years until 1999. Since the beginning of the present millennium, its celebration has been the subject of intense discussion in various Kaingang communities where a growing part of the population converted to Pentecostalism opposes its realization by invoking in particular the large consumption of fermented drink that it implies. Its recent performances have been the subject of various adjustments taking into account the local political and religious dynamics. In this paper, we describe and analyze this recent update of the Kikikoi with regard to the new social dynamics facing Kaingang culture.
