Italian Fascism is based upon Italian nationalism and in particular seeks to complete what it considers as the incomplete project of ''Risorgimento'' by incorporating ''Italia Irredenta'' (unredeemed Italy) into the state of Italy. To the east of Italy, the Fascists claimed that Dalmatia was a land of Italian culture whose Italians, including those of Italianized South Slavic descent, had been driven out of Dalmatia and into exile in Italy, and supported the return of Italians of Dalmatian heritage. Mussolini identified Dalmatia as having strong Italian cultural roots for centuries, similarly to Istria, via the Roman Empire and the Republic of Venice. To the south of Italy, the Fascists claimed Malta, which belonged to the United Kingdom, and Corfu, which instead belonged to Greece; to the north claimed Italian Switzerland, while to the west claimed Corsica, Nice, and Savoy, which belonged to France. The Fascist regime produced literature on Corsica that presented evidence of the island's ''italianità''. The Fascist regime produced literature on Nice that justified that Nice was an Italian land based on historic, ethnic, and linguistic grounds.
