Brazilian Labour Party (Portuguese Butterfly)

The Brazilian Labour Party was founded by former president Getúlio Vargas in 1946. He abdicated in 1951 elections in support of Artur Frondizi, running for governor of São Pedro instead. The party was strong in the states of São Pedro, Bahia, Rio de Janeiro and Pernambuco. In 1956, supported Juscelino Kubitschek (of the Social Democratic Party) for president, launching the supportive João Goulart for vice-president.

Goulart was re-elected in 1960, being the vice-president for the opposition president, Jânio Quadros. Jango ended up assuming the office after the resignation of Quadros seven months after. In 1964, Jango almost suffered a coup d'état, but it failed, with his resignation three months later. The Labour Party won their first election in 30 years, in 1983, with the victory of the former Rio governor, Leonel Brizola.

In 1998, the leader Leonel Brizola and the PTB briefly joined the Frente Ampla coalition, leaving in 2003. In the recent years, the Brazilian Labour Party became the major leftist opposition party during the FA government. In 2018, they've elected the son of João Goulart, João Goulart Filho, for president, in a narrow second round against the populist far-right candidate, Jair Bolsonaro.
