Post-Mandala Polities in the China–Vietnam Boundary: Rethinking Native Officials (Tuguan) in the Early Modern Period

This paper explains the political and economic factors behind the sustained influence and autonomy of the chieftains known as the native officials (tuguan/thổ quan) in the riparian regions between southwestern China and northern Vietnam. It challenges classic depictions of native officials as being mere peripheral chieftains by uncovering the institutional strength of their networks reminiscent of the Southeast Asian model of rule known as the mandala system. In this model of political organization, authority was hierarchical, charismatic, and concentric with overlapping power relationships and flexible sovereignty. Reminiscent of mandala kings in premodern Siam or the Malay states, the native officials maintained or created patron-client networks, personal vassals (or headmen), monopolies over cross-border trade, territorial designs, multiple alliances, and the collection of tribute. Waxing and waning over centuries, many native officials along the riverine frontier line preserved their spheres of influence and prevented any large states from conquering their domains. To preserve its nominal control over its side of the borderlands, the imperial Chinese state often resorted to negotiation or regime change without changing the social or institutional fabric of the native domains. The result was a collaborative relationship between early modern China and the indigenous clans not unlike the one between rulers and the nobility in early modern Europe. One party protected the other, leading to the accumulation of wealth and bolstering the legitimacy of the native officials. I argue that the native officials were powerful rulers within a network of organized domains, capable of bringing the imperial Chinese and Viet governments to the negotiating table for exercising sovereignty and controlling trade. Reminiscent of Southeast Asian kings and princes, the native officials formed power relationships and created trade monopolies across riverine boundaries.
