Résumé
Regionalist mobilizations in Italy are quite well known in the northern part while they are almost completely neglected in the Mezzogiorno. Sardinia is a southern region in which an autonomist party (the Sardinian Party of Action) has existed since 1921. This article describes its historical genesis & its main political features (electoral performance, participation to regional government) & explains its political dynamics during the Postwar period.
