The history of the Italian Republic's territorial structure has always been intertwined with party competition. Partisan logics have notably played a relevant role in the ways regions have been moulded, set up and run. This article illustrates the discourse of Italy's political parties on the ‘ordinary’ statute regions throughout the successive phases of regionalisation. After the consensus reached in the Constituent Assembly, a paralysis due to party contrasts followed. The Centre-left governments in the 1960s re-started the process, which culminated in the 1970s–also thanks to the Communists’ support–in the establishment of the 15 ordinary-statute regions. The 1990s inaugurated a period of further devolution, which reached constitutional status in the early years of the millennium. Once again, partisan motivations were of primary importance, notably because of the electoral threat posed to mainstream parties by the Northern League. In recent years, party positions have differentiated consistently according to inter-coalition competitive dynamics.
