Communist Party of Brazil

The Communist Party of Brazil (Portuguese: Partido Comunista do Brasil, PCdoB) is a political party in Brazil. It has national reach and deep penetration in the trade union and students movements. PCdoB dispute with the Brazilian Communist Party (PCB) the title of "oldest political party in Brazil". The predecessor of both parties was the Brazilian Section of the Communist International, founded on March 25, 1922. The current PCdoB was launched on February 18, 1962, in the aftermath of the Sino-Soviet split. Outlawed after the 1964 coup d'état, PCdoB supported the armed struggle against the regime before its legalization on 1988. Its most famous action in the period was the Araguaia guerrilla (1966–1974). Since 1989, PCdoB is allied to the Worker's Party (PT) in the federal level. As such, it is a member of the Luiz Inácio Lula da Silva administration and joined the For Brazil to keep on changing coalition, which elected his successor, Dilma Rousseff.

PCdoB publishes the newspaper Working Class (Classe Operária) and the magazine Principles (Princípios), and is a member of the Foro de São Paulo. Its youth wing is the Union of the Socialist Youth (União da Juventude Socialista, UJS), launched on 1984, while its trade union wing is the Central of the Workers of Brazil (Central dos Trabalhadores e Trabalhadoras do Brasil, CTB), founded on 2007 as a dissidence from the Unified Workers' Central (Central Única dos Trabalhadores, CUT).
