The spreading of public demonstrations, through papers that were named "incendiary", besides voices, screams and gestures in the streets of the capital of the Empire (Rio de Janeiro) in the decades of 1820/1830, mark a series of transformations and also the consolidation of the public spaces in the polis. In the same way, the Theater Room, in the Court, appears as a scene for this dramatization of politics, amid such handwritten, verbal and bodily expressions (which ended up remaining after the consolidation of the daily press). In general, they contained everything that could not be put into print (or even spoken) considering the set limits of that time and, yet, made it possible to reach wider sectors of the population than just the ones that were used to reading or writing. It highlights the importance of such public manifestations for the everyday politics, in a society characterized by the oral and visual communication and at the moment of the building up of the National order.
