The dissertation begins with the desire to investigate the proposal of the critique of the liberal peace to transcend the liberal logic in peacebuilding operations. This discussion requires an analysis of the discursive practices that allowed the construction of an interpretation of peace around standards and principles recognized in liberal discourses, as well as particular notions of institutionalization, democratization and liberalization. From this analysis, the research turns to the study of critical narratives that denounces the dissemination by the United Nations of a recipe for peace based on hegemonic and universalizing values, culminating in the construction, through peacebuilding operations, of an order empty of meaning in post-conflict societies. Once clarified the main points of the critical perspective of the liberal peace, it examines the possibility of transcending the liberal peace in favor of a post-liberal peace and seeks to demonstrate the paradoxes inherent to the proposal offered by the critique of the liberal peace.
