The objective of this thesis is, firstly, to analyze the reproduction of the discourse on sovereignty in International Relations, understanding it as a mechanism of fixation of identity and, secondly, to dislocate the focus of sovereignty through an analysis of mechanisms of death, considering death as object and locus of sovereignty itself. Considering queer theory’s debate on the limits of politics, the thesis engages critically with the development of this theoretical perspective in the discipline, presenting a reading that foments the dismantling of the notion of State’s uniformity and the prevalence of the international as a condition of International Relations, with the aim of understanding the international as universality. After that, in dialogue with Foucault and Butler, the thesis deepens itself in detailing the relations of power at the level of the body through the debate on subjection implied by gender identity’s fixation, demonstrating it as fundamental to the premise of rationality and agency as both founding of sovereignty. To do so, the Brazilian context of marginalization and violence against gender and race minorities is considered. Degeneration is pondered as a form of production of difference in a range of variations at the intersection of gender and race, in a critical engagement with the concept of State racism. Following that, the thesis deepens, then, a theoretical discussion around the different exercises of death over the other in order to understand the costs of the expansion of life, evidencing the constitutive violence of the formation of a sovereign identity. The thesis then proposes an analysis of death as key to the agency of the being and to sovereignty, departing from a reading of bataillean excess. Sovereignty is analyzed in flirting with death, both in slow death as in violent death, both in between consciousness and its interruption, and in between utility and expenditure. Thus, identitarianism is put in check through the questioning of agential capacity reduced to reason, in a contribution that departs from the loss of the self as a contestation of the image of the individual and the sovereign State. Finally, the proposal of an alternative conception of sovereignty is examined by recovering the discussion about queer radicality and about the consequences of the movement of denaturalization both of gender as well as sovereignty, be them significative in terms of resistance or not.
