Further problems continue to arise in part due to the shaping of the modern Malaysian and Indonesian nation-states on post-colonial political systems and laws on land tenure. The conflict between the state and the Dayak natives on land laws and native customary rights will continue as long as the colonial model on land tenure is used against local customary law. The main precept of land use, in local customary law, is that cultivated land is owned and held in right by the native owners, and the concept of land ownership flows out of this central belief. This understanding of "adat" is based on the idea that land is used and held under native domain. Invariably, when colonial rule was first felt in the Kalimantan Kingdoms, conflict over the subjugation of territory erupted several times between the Dayaks and the respective authorities.
