Among the factors highlighted by the literature as crucial for the success of cohesion policies in generating satisfaction among citizens, and therefore in acting positively on the constitution of an European identity, this paper emphasizes a particular one, territorial identity. Elaborating on the definition of territorial identity as a local condition in which private interests coincide with public ones, the paper claims that territorial identity plays an important role in a European identity‐building process. In fact, by increasing the probability that local public expenditures match private interests, territorial identity generates a favourable context where the critical factors that hamper the successful programming, design and implementation of cohesion policies can be overcome.
