This study traces long processes of ethnic politics in West Kalimantan, Indonesia. It argues that ethnicity has always been a component in the hybrid state throughout the contemporary political history of the region. By employing the concept of hybridisation, the study reveals that the weak degree of the hybridised state during the Soeharto era has become a necessary condition for the rise of ethnic violence. Only recently, the reconstruction of the benevolent hybrid state may gradually prevail. The existence of power sharing among ethnic elite, the democratic and peaceful gubernatorial direct elections that have taken place, and the inter-ethnic economic co-operation among ordinary citizens could make ethnicity develop in a constructive way as one of basic components within the hybrid state. Qualitative method has been used to collect data from various actors who have direct and indirect knowledge both during and after the Suharto eras.
