In 1792, Tiradentes was hanged in the campo de São Domingo — a square that today bears the sentenced man's name — in a spectacle meant to serve as an example to those who dared question the authority of the Portuguese Crown. Two years later, however, the viceroy of Brazil, José Luís de Castro, Count of Resende, was scandalized by reports of secret meetings, in which colonists were debating the very same ideas that had sent the Minas Gerais conspirator to the gallows.

The viceroy had reasons to be terrified. Enlightenment authors, such as Voltaire — or Vulter, in his Brazilianized version —, and periodicals that reported on and extolled the course of the French Revolution were forbidden from circulating among the colonists. They eroded the legitimacy of the government. In the view of the colonial administration, these "seditious and incendiary writings" planted "the seed of insurrection among the subjects of their respective sovereigns." And to the Crown's despair, the "hateful Frenchisms" sometimes escaped Portuguese censorship and went on to stir the political imagination of the colonists.
Um grupo de letrados, em especial, passou a se reunir para discutir aqueles ideais revolucionários — this group, in particular, began meeting to discuss those revolutionary ideals. The meetings took place weekly, at the house of the poet Manuel Inácio da Silva Alvarenga, on Rua do Cano, today's Rua Sete de Setembro. That was where the Sociedade Literária do Rio de Janeiro operated — an association initially with academic and scientific purposes, but which, in 1794, had turned into a space where the common good, equality, republic, and democracy were debated. Most of its members were doctors and apothecaries. The meetings were secret, but the ideas spread, taking on new directions as soon as night turned into day.

On Rua do Cano, the city's main apothecaries operated. There, the population of Rio de Janeiro would order their medicines, ointments, and the like. These establishments were conducive to the spread of those subversive conversations: it was enough for the customer to prick up their ears, listen to what the doctors and apothecaries were saying, and mull over the content of that dialogue themselves — that is, when they didn't chime in on the gossip. From the apothecary counters to public spaces such as Mestre Valentim's fountain, in what is now Praça Quinze de Novembro, ideas spread through the air at the speed of sound.

Upon being informed of the existence of these gatherings, the Count of Resende decided to root out the evil at its source. He banned the activities of the Sociedade Literária and had eleven of its members imprisoned in the fortress on Morro da Conceição. The so-called Conjuração do Rio de Janeiro did not amount to a plan to overthrow colonial power. But the viceroy of Brazil, fearing the greater evil, kept the suspected intellectuals locked up for two years, without formal charges.
