El Norte Grande durante el Ciclo del Salitre: La política salitrera y la política exterior en la formación de un es pacio trans fronterizo (Bolivia y Chile, 1880-1929)

It is said here that the social and organizational creation of the Big North would be related to the politics of saltpetre and foreign policy of Chile after the War of the Pacific. A hypothesis is suggested about how important the "saltpetre tax" is (1880) as the beginning of the social construction of cross-border space. In this work both public policies are analysed that, during the first period between 1880 and 1904 would agree to allow the cross-border regions to be related to the saltpetre industry through the circuit of goods and people. In that period the Chilean state would develop its "Bolivian policy" of detente with that country and would have an economic role of rentier state and politically out of the saltpetre regions. Between 1904 and 1929 those roles would be changed by more active ones, where the diplomacies of Bolivia and Chile start their law suits and the borders in transition are made stricter to make up the current international borders of the Big North of Chile.
