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.
