This dissertation examines the constitutional order initiated by the 1891 Constitution along with the decade of chaos (1889-1898) that followed the Proclamation of the Republic, in order to investigate how the conflict in Canudos (1893-1897) became politically significant and what role did it played in the consolidation of the republican political order. The Republic withdrew the Moderating Power from the political arena, which until then was the main institutional mechanism for solving political conflicts. With its absence, various tensions emerged in both political and civil spheres emerged. The resulting disorder spread to all levels of the federation, as legislative groups were formed under the influence of state political leaders. The dissertation explores the tensions between Executive and Legislative power, at both national and state levels, drawing on selected bibliography and focusing on Bahia. This work also evaluates the impact of the ongoing war on political and institutional actions, based on a range of sources, including letters from relevant figures, public speeches and press articles. The conflict in Canudos emerged from the republican entropy and became a pivotal moment for Prudente de Morais, allowing the president to isolate key elements that promoted destabilization within the Republic. Through this, he was able to ensure a relatively orderly succession to the new civilian presidency.
