The present work aims to unveil the terms in which the physical and ontological security (thought as practice and discipline) must be articulated on International Relations scholarship to respond to the demands of indigenous women. Departing from a decolonial and anti-colonial theoretical discussion, I seek to fill the existing disciplinary gap regarding the discussion of the different forms of violence inscribed on the bodies of indigenous women as part of the colonial legacy in the modern state. To this end, this work articulates Célia Xakriabá s concept of corpo-território (2018) as a central axis for understanding the ways in which the State and the International act in the creation of frontiers between life and death over indigenous bodies and territories. Based on a feminist and decolonial methodology, the theoretical discussion is empirically illustrated with the case of women from the Guarani-Kaiowá people and their territorial and bodily autonomy demands. In this sense, this work unfolds from two related questions: how do indigenous women articulate the relationship between body, territory and security? And how does this form of articulation allow us to reframe the approach about the body and territory in the feminist critical security literature in International Relations? By answering these questions, this work demonstrates that it is not possible to think about indigenous women s dynamics of (in)security without considering the corporeal-territorial dimensions of their resistance.
