What were the changes in the international position of the Brazilian state during the Lula and Cardoso administrations? How were the classes and class fractions represented? These are the questions that Tatiana Berringer's work seeks to answer. Using the theoretical instruments of the Marxist Nicos Poulantzas, the book identifies the class interests that directed the international action of the Brazilian state. With notable originality, the text presents, theoretically and empirically, a truly consistent Marxist analysis of Brazilian foreign policy, as well as a rich interpretation of the class struggle in current Brazilian politics. The author offers the reader her reflections on the political crisis of 2016 and the foreign policy of the Dilma, Temer, and Bolsonaro governments.
