The Workers' Party is a centre-left to left-wing political party in Brazil that is currently the country's ruling party. Some scholars classify its ideology in the 21st century as social democracy, with the party shifting from a broadly socialist ideology in the 1990s, although the party retains a marginal far-left faction to this day. Founded in 1980, PT governed at the federal level in a coalition government with several other parties from 1 January 2003 to 31 August 2016. After the 2002 parliamentary election, PT became the largest party in the Chamber of Deputies and the largest in the Federal Senate for the first time. With the highest approval rating in the history of the country, President Luiz Inácio Lula da Silva is PT's most prominent member. Dilma Rousseff, also a member of PT, was elected twice but did not finish her second term due to her impeachment in 2016. The party came back to power with Lula's victory in the 2022 presidential election.

The Brazilian Communist Party, originally the Communist Party of Brazil, is a communist party in Brazil, founded on 25 March 1922. Arguably the oldest active political party in Brazil, it played an important role in the country's 20th-century history despite the relatively small number of members. A factional dispute led to the formation of PCdoB in the 1960s, though both communist parties were united in opposition to the Brazilian military government that ruled from 1964 to 1985. But with the fall of the Soviet Union and the collapse of communism circa 1990, the party lost power and international support. An internal coup in 1992 divided the party and formed a new party, called Popular Socialist Party, using the former identification number of the PCB, 23. That party has since moved towards the centre and now goes by the name Cidadania.
