This study is an intervention in early modern global diplomacy. Integrating an indigenous community of the Philippines into foreign relations and maritime connections, the article reevaluates the complex story of the Pampangans of Luzon, allegedly long-term allies of the Spanish conquerors, and the narrative of indigenous collaboration. Foregrounding the Pampangans’ involvement in military campaigns, as well as territorial and maritime expansion in the early decades of the 1600s, the article introduces three scenarios of Pampangan power bargaining with global consequences. The focus on Pampangan foreign relations opens new analytical perspectives on the role of language and knowledge for internal coloniality on the one hand, foreign and diplomatic negotiations on the other. Methodologically, it proposes a deep (re-)reading of the polyvocal archive of the colonial-indigenous encounter and integrates insights with the largely separated scholarship of diplomatic and indigenous history as a new avenue in global history.
