This paper intends to contribute to the theoretical and methodological debate on regionalization and history. Firstly, it starts discussing the very concept of region on its several related approaches: geography, political economy, history and historiography. Then, a methodological issue is analyzed, that is to say: the paper tries to articulate the most important criteria of spatial segmentation embedded on regionalization (analytical functionalism, heterogeneity and homogeneity) with: a) the necessity of non-anachronism; and b) the necessity of a historical dynamic approach on definition of regional boundaries.
