The PFR did not outlast Mussolini's execution and the disappearance of the Salò state in April 1945. However, it inspired the creation of the Italian Social Movement (MSI) and the MSI has been seen as the successor to the PFR and the PNF. The MSI was formed by former Fascist leaders and veterans of the National Republican Army of the Salò republic. The party tried to modernise and revise fascist doctrine into a more moderate and sophisticated direction.
