This commentary revisits the main elements of Paasi's ideas about the institutionalisation of regions and bounded spaces. It reviews his analysis of the identity of a region and the regional identity of its residents (as addressed in his TESG 2002 article). Next, it discusses how his work on bounded spaces contributed to the reinvention of border studies in political geography and how his innovative conceptual work grounded in and written from Finland, was inspiring for a whole generation of researchers working at the margins of the Anglo‐American academic world. Finally, it reasserts the enduring value of his heuristic framework in a time where the complexity of social spatialisation and of spatial socialisation has greatly increased.
