The paper intends to build up a theoretical approach in order to think the Amazon borders and its contemporary perspectives in a moment when development and environmental sustainability insert it in the debate. Departing from formulations about the theme and the process of frontiers' expansion in the 1960's, we identified the contributions and the limitations of the concept of borders adopted by the authors. More the identifying the actions over a border region, we theorised about the construction of a concept, demonstrating that a mechanism that builds up the border and names a region such as a “frontier” is a mechanism of power.
