Pursuing defragmentation at the municipal level: signs of a changing pattern?

Municipal fragmentation is a real historical issue in Italy but its relevance has been differently perceived over time. With a focus on the municipal unions and amalgamations as the main tools for defragmentation, we will present an overview of the last quarter century (1990-2017) of territorial policy at the local level. The reforms introduced since 2010 marked a step change in this area: in fact, empirical evidence shows that the most recent defragmentation attempts have had a certain success. This article, by maintaining a descriptive approach, will try to answer why the most recent defragmentation policy achieved some results, in contrast to those of the past. Some explanatory factors will be presented by reviewing the stances of the main actors in this policy field and their interaction with national policy-maker goals and approaches as well as with normative elements and external conditions.
