Mapmaking and Sovereignty Building: Francisco Requena and the Late Eighteenth-Century Boundary Demarcation Commissions
Bibliographic record
Abstract
Abstract After signing the 1777 Treaty of San Ildefonso, Spain and Portugal sent joint expeditions to demarcate their South American borders, as they had done a quarter century earlier. Focusing on the activities of Spanish commissioner Francisco Requena in western Amazonia in the 1780s and 1790s, this article shows that such efforts were not limited to confirming in loco the lines drawn in European courts. I demonstrate how Indigenous populations played on Iberian rivalries to maintain their autonomy and negotiate their resettlement. The very interactions between commissioners and Indigenous peoples intensified the porosity of border spaces. Because commissioners believed that sovereignty was defined through monarchical loyalty rather than simply lines on a map, they contributed to the movement of people and goods across the dividing line that they intended to create, making the border even more permeable to Indigenous claims to territoriality and cross-border interactions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
