This M.A. thesis focuses on the political demonstrations of the jacobinos and on their rhetoric in the City of Rio newspapers, from 1894 until 1897. By identifying their main ideas and proposals, and by analyzing their intense opposition against the first civilian president of the Republic, Prudente de Moraes, it is my goal to review the historiography hitherto produced in order to better characterize the jacobinos under this transition period from military to civilian order. I argue that jacobinos opposition to Prudente can be analytically divided into two different phases: an initial one, in which the jacobinos demonstrations went hand by hand with their fighting the dissolution of the patriotic battalions and of corporatist interests; and a second one, marked by their fear of change, in view of then wide propaganda and gathering of monarchists and restoration-driven individuals around Prudente. The jacobinos longed for the conservation of the militaryoriented policy and the war-like situation the civilian president inherited from his predecessor Floriano Peixoto. They wanted to keep the rewards and acknowledgements they benefited from, for joining the patriotic battalions. The identification of such jacobinos ideas and proposals for the Republican regime allow us to portrait them differently and, mainly, to question a few odd views about them which still prevail in the standard historiography from the 1980s to the present.
