The Party of the Istalian Revolution (PRI) was a neo-Battistian political party in Istalia. The party was founded in 4045, in the wake of the Istalian Civil War. The bulk of its early membership consisted of supporters of the 4042–4045 Battisti dictatorship, and included figures such as Roberto Cappato and former Prime Minister Vittorio Albertini. The latter was elected the first leader of PRI in 4045.
