Theories used in the Information Systems (IS) field come in large majority from authors based in Western countries, a bias that holds for critical theories as well. Such a bias is made more problematic by the mandate of critical theory, which is meant exactly to illuminate the oppressive conditions of the status quo. Against this backdrop, this paper explores the subalternity theory approachdeveloped by the Subaltern Studies collective from the early 1980sas an indigenous theory that, proposing a socially and geographically connotated narration of 'history from below', can play a major role in the effort to decolonise critical IS research. By positioning subaltern theory in the IS field, the paper offers an alternative to the Western hegemony of critical theories, exploring the potential of such an alternative to voice systematically silenced and marginalised perspectives.
