The Orang Batin Sembilan, Orang Rimba or Anak Dalam are mobile, animist peoples who live throughout the lowland forests of southeast Sumatra. Kubu is a Malay exonym ascribed to them. In the Malay language, the word Kubu can mean defensive fortification, entrenchment, or a place of refuge. It is metaphor for how the majority and dominant Islamic Melayu villagers believe them to use the interior forests as a means for resisting inclusion in the larger Malay social and Islamic religious world. As is the case with other forest peoples in the region, the term Kubu is associated with very negative connotations.
