Outline of Final Research Achievements

This research revealed that the Burma;Thailand border was shaped not merely by imperial fiat, but through negotiations deeply embedded in ethnographic classification and field encounters. British and Siamese surveyors used inconsistent and often politicized ethnic categories to map and legitimize territorial claims, effectively “placing” certain groups on one side of the border to serve strategic goals. Rather than creating a clear boundary, this process produced zones of ambiguity where identity and sovereignty overlapped. The study demonstrates that ethnic classification was not just a tool of governance but a dynamic force that influenced the very contours of the state. These findings challenge conventional, top-down accounts of border formation by showing how local knowledge, political interest, and ethnographic practice worked together to shape territorial order in mainland Southeast Asia, offering new insights into the co-production of identity, space, and sovereignty.
