The 1964–1985military dictatorship in Brazil engaged in censorship of media, artists,journalists, and others it deemed "subversive", "dangerous", or "immoral".[1][2] The political system installed by the1964 coup d'état also set out to censor material that went against what it calledmoral e bons costumes ('morality and good manners').[3]
The government prohibited the production and circulation of such material. In addition to foreign books andauthors, especially those social and political in nature, about 140 books by Brazilian authors were forbidden by the state in that period, covering both fiction and non-fiction.[1] Among these Brazilian authors there wereÉrico Veríssimo,Jorge Amado,Darcy Ribeiro,Rubem Fonseca,Caio Prado Júnior,Celso Furtado,Ignácio de Loyola Brandão,Dalton Trevisan,Maria da Conceição Tavares,Olympio Mourão Filho, and others.
At the beginning of the military dictatorship, between the coup in 1964 andInstitutional Act Number Five in 1968, censorship involved confiscation initiatives withphysical coercion by poorly trained agents atrandom checkpoints.[1]
Throughout the dictatorship, the hierarchical structure of organs involved in censorship went through transformations.[4] TheServiço de Censura de Diversões Públicas was originally established December 26, 1945, underGetúlio Vargas.[4][5] With the aim of centralizing censorship activities and standardizing directives, theDivisão de Censura de Diversões Públicas [pt] (DCDP) was created June 2, 1972, as part of theFederal Police of Brazil, subordinate to theMinistry of Justice and Public Security.[4]
Ênio Silveira, editor ofCivilização Brasileira [pt], was jailed and tried several times; in May 1965, his arrest prompted apetition signed by about a thousand people working in culture.[1]
Theconstitution of 1967 [pt] made censorship an official, centralized activity of the federal government inBrasília.[1]

Two protests against the military dictatorship precipitated the AI-5: theCultura contra Censura protest against the prohibition of 8 plays in February 1968 and theMarch of the One Hundred Thousand in June of that year.[1]
On December 13, 1968, theInstitutional Act Number Five was announced in the name of "authentic democratic order [...] (and) the combat of subversion and of the ideologies contrary to the traditions of our people", creating conditions under which disclosure of information, manifesting opinions, and cultural and artistic production were subjected to censorship.[1]
The death of journalistVladimir Herzog in 1975 is considered a turning point in the process of Brazil's re-democratization.[6][7] The military regime promulgated a narrative that Herzog had committed suicide, but evidence indicated that the suicide had been staged, leading to public protest against the military government and its methods of covering uptorture, including a weeklong strike by 30,000 university students and professors.[6]

The January 1977Manifesto dos Intelectuais 'Petition of the Intellectuals' led byLygia Fagundes Telles, with over a thousand signatures against the dictatorship, was delivered to theMinistry of Justice in Brasília and broke the momentum of the censors.[8]
On October 13, 1978,Constitutional Amendment No. 11 revoked the AI-5, effective January 1, 1979.[1]Zuenir Ventura estimates that in the decade in which the AI-5 was in effect, approximately 500 films, 450theatrical plays, 200 books, dozens ofradio programs, 100magazines, over 500 song lyrics and a dozentelenovela titles and pilots were censored.[1]
Caetano Veloso andGilberto Gil were arrested December 27, 1968—days after AI-5 was announced—under the false accusation of having performed a parody of theBrazilian National Anthem to the tune of"Tropicália" at the Sucata club in Rio de Janeiro.[9][10][11][12][13] They joined a number of Brazilian artists who lived in exile during the military dictatorship.
Some artists responded to the climate of censorship and repression by cleverly disguising subversive messages in their work.[14] Notable examples includeGeraldo Vandré's 1968 "Pra Não Dizer que Não Falei das Flores" as well asChico Buarque's 1970 "Apesar de Você [pt]" and 1973 "Cálice."[14]
Some newspapers adopted strategies—such as printing excerpts fromLuís de Camões's 16th-centuryOs Lusíadas or cake recipes calling for a 1 kilogram (2.2 lb) of salt—to indicate to readers that the content in those sections had been censored.[15][16] So much material was censored fromO Estado de S. Paulo between December 1969 and January 1975 that it printed all 8,116 verses of theLusíadas twice over.[16]
