How Brazil’s largest political party emerged from the ashes of a military dictatorship
In short: Brazil Union was born from a strategic merger between two major right-wing parties, aiming to consolidate power and navigate a polarized landscape. By blending the lineage of a former military regime with modern liberal-conservative ideals, the party seeks to capture voters disillusioned by the country's recent political extremes.
The Brazil Union, or União Brasil, officially formed on October 6, 2021, following a merger between the Democrats and the Social Liberal Party. This union was formally sanctioned by the Superior Electoral Court on February 8, 2022. The party’s roots are complex; the Democrats traced their history back to the National Renewal Alliance, which functioned as the governing party during Brazil’s period of military rule. Meanwhile, the Social Liberal Party had shifted from its original social-liberal roots toward economic liberalism and social conservatism following the rise of Jair Bolsonaro.
The merger was driven partly by Constitutional Amendment 97, enacted in 2017, which introduced a barrier clause that restricted federal funding and media access for smaller parties, while banning coalitions in proportional elections. These rules incentivized consolidation to ensure political survival. Despite initial internal resistance from figures like ACM Neto, who feared the move would dilute the parties' influence, the merger proceeded. However, the transition was not seamless; many core supporters of Jair Bolsonaro departed for other groups, such as the Liberal Party, as the new organization sought to field its own presidential candidate.
Ideologically, the party positions itself as centre-right, advocating for fiscal austerity and privatization while rejecting the concept of a minimal state. It maintains that government intervention remains essential for healthcare, education, and social programs. Furthermore, the party distinguishes itself among pro-business groups by explicitly acknowledging climate change and calling for government mitigation efforts. In the 2022 elections, the party nominated Soraya Thronicke for president and saw success in gubernatorial and legislative races, including the election of former judge Sergio Moro to the Senate. By 2025, the party further expanded its influence by forming a legislative alliance known as the Progressive Union.
The party’s manifesto emphasizes four core pillars: the importance of democracy, the state as a guarantor of social rights, individual freedom, and the family as the foundation of society. While it accepted three ministry posts in the administration of Luiz Inácio Lula da Silva, party leadership has maintained that it is neither part of the official government base nor strictly in opposition, reflecting a desire to carve out a distinct path between the country's two dominant political figures.
