Liberal Alliance (Portuguese Butterfly)

The Liberal Alliance was a coalition, then a political party formed by a merge of regional parties and the Liberal-Republican Party to support the candidacy of Getúlio Vargas in the presidential election of 1930 and end the long-running term of the Republican Party of São Paulo.

When Vargas was elected, the party established an absolute majority in the National Congress until the second term of Américo de Almeida, when the most progressive and left-leaning factions of the party, dissatisfied with Américo's government, broke up and founded the Labour Party with Vargas. The remaining portions formed the Centrist party, Social Democratic Party, while a dissident portion merged with former São Paulo politicians and established the modern Republican Party.
