Faced to the Pacificacion de la Araucania and the Conquista del Desierto, the colonization of Tierra del Fuego -another violent episode of territorial dispossession begun in 1884- can be distinguished by three criteria. In the first two cases, the State commanded military campaigns for the appropriation of new land; in the second, Chile and Argentina had already considered it as their property (Boundary Treaty of 1881) and they simply offered land concessions to sheep-farming investment, transferring at the same time the task of Indian eradication. In the first cases, national armies opened the trail for cattle; in the second, there were just a couple of police stations helping sheep-farmers in the expansion of sheep. Accordingly, if violence in the Pacificacion and the Conquista was the interruption of political relationships between conquer and conquered, in Tierra del Fuego it was told to initiate civil life. Finally, in the first cases, the price of defeat was for the conquered to become an Indian; in the second, without a political frame, sheep-farmers produced the savage conditions they were fighting against. The article will ask about this production and will offer evidence about the formation of civil power in Tierra del Fuego.
