[pt] Entre 1835 e 1852, Juan Manuel de Rosas estruturou o segundo mandato como governador de Buenos Aires através de amplos poderes, forte propaganda e censura, coerção política e violência. O objetivo era criar uma esfera de unanimidade, entendendo que esse caminho levaria as Províncias Unidas do Rio da Prata à ordem republicana, tão desejada desde a década de 1820. Se na cidade de Buenos Aires havia a presença do governo nos âmbitos público e privado, em um cenário de autonomia das províncias a relação de Rosas com os governadores encontrou formas específicas para se organizar, fazendo com que o período em que esteve como governador fosse diferente de tudo que as Províncias Unidas já haviam passado até aquele contexto. O presente trabalho pretende, então, identificar determinadas ações do governo de Rosas a partir de 1835 para com as províncias presente nas cartas aos governadores e na imprensa oficial para entender os caminhos escolhidos pelo líder em busca da consolidação de um governo conhecido como autoritário que se utilizou do discurso federal. / [en] Between 1835 and 1852, the second term of Juan Manuel de Rosas as governor of Buenos Aires was defined by his use of broad powers to control the press, as well as executing censorship, political coercion and violence. His objective was to create a sense of unity, with the promise that this path would take the Provinces of Rio da Prata closer to a Republican ideal, a political system that had been sought for since the 1820s. Although the presence of the government in the city of Buenos Aires was strong both in the public and private spheres, the provinces enjoyed more autonomy. Rosas reorganized the relationship with each region, so that the period in which he was governor was different from everything that the United Provinces had previously experienced with regards to the political relationship between local provinces and the central government. The present work intends to identify certain actions of Rosas government from 1835 in the provinces available in the letters to the governors and the official press to understand the paths chosen by the leader for the consolidation of a government that, although it used the discourse of federalism, is widely held to be authoritarian.
