To go deeper into his knowledge of the bloody conflict (over 30,000 dead), which tainted the history of Brazil between 1912 and 1916, and which was virtually silenced due to the greater "media" investment in World War I that occurred in Europe, Nilson rescues the role of the identity and importance of the Contestado in the territorial formation of the South of Brazil. With the mastery and detail of a passionate about the subject, he retrieves documents and convincingly shows the established structure between the society, the economy, the culture and the politics that, in an intricate way, weave the scene of the war and its consequent outcome in favor of the elites who participated in it. Through the questions raised, we hypothesize that the Contestado was a decisive landmark for the definition of the territory, the region and the road network in the disputed area. The definition of this triad [network, territory and power] would have been evidenced, before the conflict, mainly by the internal dynamics of the region itself, but with the advent of the republic and modernity, the external situation is that it began to define the specificities of this triad in the Contestado area.
