Brazil Union

The Brazil Union (Portuguese: União Brasil, UNIÃO) is a liberal-conservative political party in Brazil. The party was founded on 6 October 2021 through the merger of the Democrats (DEM), thus tracing its lineage to ARENA, the governing party of Brazil’s military dictatorship, and the Social Liberal Party (PSL). The merger resulted in the biggest party in Brazil, and was approved by Brazil's Superior Electoral Court on 8 February 2022. The party is generally split on opposition to Jair Bolsonaro and is most often in opposition to the policies of Luiz Inácio Lula da Silva, nominating Soraya Thronicke for president in 2022 Brazilian general election. In 2022, it was reported the party was in talks with the Progressistas to form the largest bloc in Congress. The formation of the alliance, the Progressive Union, was approved in April 2025, making the broader federation, the largest bloc in Congress.
