Negotiated Nations: State Formation, Indigenous Politics, and Land in the Chiapas-Guatemala Borderlands, 1780-1910 This dissertation explores the history of the disputed borderlands between the Mexican state of Chiapas and Guatemala from 1780 through 1910. An innovative transnational study of state formation, it examines how ethnic conflict, community politics, and land disputes in these borderlands challenged, shaped, and advanced the construction of state and nation in Mexico and Guatemala. In doing so, it centers the Indigenous communities that lived and worked in this supranational region, locating critical junctures where they challenged the inevitable consolidation of the Mexican and Guatemalan nation-states and conceived of alternative political futures for themselves.
