Press, politic, and social order in Buenos Aires during the 1850s

The paper examines some reflections and discussions about the role and nature of the press that took place in Buenos Aires during the 1850s, referring to the difficulties involved in congenial freedom and order. This was caused by the fact that the press was considered a pillar of republican and civilized societies, but also an agent capable of corroding the social and political order.
