This work aims to analyze the socio-political and economic bases of the riseof conservative-authoritarian right-wing populism in Brazil between 2016 and 2022, personalized and vocalized by then-presidential candidate Jair Messias Bolsonaro. To do this, we identified and analyzed the circumstantial and structura lfactors that made it possible for a former federal deputy to rise to the country shighest office, until then without political expressiveness and contesting the election for a political party without national capillarity. We argue that the victoryof the former Brazilian Army captain is part of the global phenomenon of contemporary populism in the wake of the crisis of representativeness in democratic countries, but that in the Brazilian case it has its own specificity. Unlike many Western European countries and the United States, Brazil has a poorly institutionalized party system and a majority of votes are personalist, which favours populist adventures. Even so, there were conjunctural and structural factors that promoted the greater insertion and growth of the right in the country, after 13 yearsof Workers Party governments at the national level, as well as factors associated with the June 2013 protests, Lava Jato Operation, Dilma Rousseff s impeachment process, the emergence of the conservative and customs agenda in the public sphere. These circumstances favored, for the first time in Brazilian political history, through the popular vote, the election of a candidate directly identified with the right-wingmovement. In this way, the populist political-electoral strategy was organized around five pillars of socio-political and economic support: lavajatismo (Lava Jato Operation) and antipetismo (anti left-wing party), the military, evangelicals, agribusiness and social networks. In the Executive Branch, from 2019, Bolsonaro sright-wing populism has established troubled relations with the other branches of government, especially the judiciary, and with sub-national governments, as wellas supporting anti-democratic demonstrations. We can therefore conclude that bolsonarismo, as a political movement, has a more structural than conjunctural character due to its capillarity in the socio-political and economic segments ofBrazilian society.
