My research centers on the transformation of Brazilian geopolitical thought between 1985 and 2010, specifically examining the dynamic interactions, structural continuities, and discursive formations of three major geopolitical traditions: Grandeza (Greatness), North-Atlantic Alignment, and the Global South tradition. Geopolitical traditions function akin to Braudelian longue durée structures: they appear as stabilized organizing principles within the deep layers of foreign policy, defining the country's international scope of action. The competition between these traditions, and the interest-maximizing activities of the agents driving them (military elite, technocrats, diplomats, intellectuals), appear as causal factors in the foreign policy shifts of the democratic transition, contributing to crises and reconstructions of state identity. The shifting dominance of specific traditions and the struggle for hegemony play a pivotal role in shaping regional integration efforts (Mercosur, UNASUR) and global ambitions (IBSA, BRICS). My primary objective is to uncover the synthesis and friction points of these three traditions using the toolkit of Critical Geopolitics. This approach allows for a deeper understanding of the internal logic of the Brazilian "geopolitical imagination" and substantiates the argument that the success of the BRICS formation lies precisely in its ability to simultaneously satisfy these three seemingly contradictory traditions.
