Using a case study of the election of an adat head (kepala adat) in a Medang Dayak community in East Kalimantan, Indonesia, this study investigates the effect of large-scale oil palm land acquisition on the social structure of an adat community in terms of the ability of adat leaders to consolidate their positions within the social hierarchy. The findings highlight that the introduction of the oil palm to the community has weakened adat authority. However, it has also raised the community’s hopes that the ideal form of adat authority will still be able to handle internal tensions and external pressures.
