The historiography of Argentine theater has, at present, an important disciplinary challenge: to chronicle the complex processes of regionalization of the “national drama” to avoid the homogenization and the poetic-conceptual reductionism of the scenic diversities registered in the peripheral zones. Therefore, in this article I propose a critical reflection on these epistemological debates, through a conceptual review of operational tools from human geography and contemporary cultural studies that, among other results, allow us to formulate an effective theoretical-methodological strategy for historiography of regional theater.
