This study reconstructs life in the southern Mindanao highlands from the mid-nineteenth century to the early twentieth century from historical accounts and contemporary ethnographic observations. It explores the evolving relationships among highland groups, referred to as “atas,” “ata-as,” or “ataas,” and other communities in the region. Such terms, later recognized officially as “Ata,” were used by non-highlanders to denote highland communities based on their geographical location, while they self-identified according to upland river configurations.
This study reveals that various named groups inhabited a three-tier highland/inland-to-lowland/coastal axis, engaging in both cooperative and adversarial interactions, such as trading and slave-raiding. By the time Spanish authorities established the Davao pueblo, the highlands were already a dynamic, inhabited space, independent of colonial influence. The Pantaron highlands emerged because of long-term, cumulative decisions by these communities, reflecting a complex history that predates colonial dynamics. The findings challenge colonial-centric narratives and emphasize highlander agency in shaping their social and geographical landscape.
