Lula da Silva s government (2003-2010) has been approached in Brazilian Foreign Policy Analysis (BFPA) mainly under a framework of change versus continuity. Nonetheless, the way the area assesses change and continuity might need to be framed differently and, if either change or continuity are found, it might be of a different kind than the literature has established so far. An illustrative result of this is a reduced capacity of the field to understand the recent turn towards the far-right in Brazil and how the strong polarization and memory disputes over the Lula and Dilma governments could relate to foreign policy, for example. Those recent movements seem to defy the regular cost-benefit calculus, as well as to consider the deep influence between domestic discourses of identity and official Foreign Policy. Therefore, I propose to look at post-structuralist and constructivist approaches to foreign policy and identity and national biographies that analyze foreign policy discourses in the context of a Lacanian ontology of lack and anxiety, which leads to the country s continuous search for (impossible) stability and ontological (in)security. Understanding foreign policy as discursive practices drawing frontiers between the domestic and the international and the biographical narratives of past, present, and desired future, the literature suggests a central role to master signifiers and the libidinal investments over them. Henceforth, the main contribution of this thesis is presenting the (re)construction of Brazilian biographical narratives under the lenses of the analysts of BFPA, which includes both politicians and academicians, aiming to map the master signifiers around which their hegemonic narratives circulate. According to the field, the master signifiers found guiding Brazil s hegemonic biographical narratives were miscegenation/racial democracy, legalism/pacifism, development, and autonomy. Around those, many other relevant ones circulate. Later on, those master signifiers and their chains of significance were contrasted to the official BFP discourses during Lula, trying to understand if and to what extent Lula s Foreign Policy discourses could have dislocated meaning over Brazilian identity narratives. This thesis pays special attention to racial discourses and their relation to a sense of ontological insecurity of the Brazilian self. Not aiming to present definitive answers to the matter and finding many elements of complexity and discursive ambiguity during Lula, also taking into consideration the sliding/shifting nature of signifiers, one of the main objectives of this work is to show the constructive role of the BFPA academia in Brazil’s understandings of its biographical narratives. Another central goal is to explore how the realm of domestic identity discourses, part of foreign policy, actively inform and/or limit official Foreign Policy and how this one influences back Brazil s domestic understandings of self and other (foreign policy). Such an approach disrupts the traditional idea of Foreign Policy as a bridge between the domestic and the international. Differently, takes it as a discursive construction entrenched to libidinal and imaginary narratives, anchored by master (and sliding) signifiers, of its self or ego, as well as the ideal of the ego and the others.
