The Ato Institucional Número Cinco – AI-5 (English: Institutional Act Number Five) was the fifth of seventeen major decrees issued by the military dictatorship in the years following the 1964 coup d'état in Brazil. Institutional Acts where the highest form of legislation during the military regime, given that, issued on behalf of the "Supreme Command of the Revolution" (the regime's leadership) they overruled even the Nation's Constitution, and were enforced without the possibility of judicial review.

AI-5, the most infamous of all Institutional Acts, was issued by President Artur da Costa e Silva on December 13, 1968.

Written by then Minister of Justice, Luís Antônio da Gama e Silva, it came as a response to earlier events such as a march of over fifty thousand people in Rio de Janeiro to protest against the murder of student Edson Luís de Lima Souto by a member of the Military Police of Rio de Janeiro, the March of the Hundred Thousand, and the decision of the Chamber of Deputies denying authorization to prosecute Congressman Márcio Moreira Alves, which called Brazilians to boycott the celebrations of September 7 (Independence of Brazil). It also came to consolidate the ambitions of a group inside the military, known as "hardline", unwilling to give the power back to the civilians anytime soon.

Dario Fo (born 24 March 1926) is an Italian satirist, playwright, theatre director, actor, composer and recipient of the 1997 Nobel Prize in Literature. His dramatic work employs comedic methods of the ancient Italian commedia dell'arte, a theatrical style popular with the working classes.

Fo's works are characterised by criticisms of organised crime, political corruption, political murders, most of the Catholic Church doctrine and conflict in the Middle East. His plays often depend on improvisation, commedia dell'arte style. His plays, especially Mistero Buffo, have been translated into 30 languages and, when performed outside Italy, they are often modified to reflect local political and other issues. Fo encourages directors and translators to modify his plays as they see fit, as he finds this in accordance to the commedia dell'arte tradition of on-stage improvisation.

Fo currently owns and operates a theatre company with his wife, actress Franca Rame. Upon awarding him the 1997 Nobel Prize in Literature, the committee highlighted Fo as a writer "who emulates the jesters of the Middle Ages in scourging authority and upholding the dignity of the downtrodden".
