Populism raises awkward question about modern forms of democracy. It often represents the ugly face of the people. It is neither the highest form of democracy nor its enemy. It is, rather, a mirror in which democracy may contemplate itself, warts and all, in a discovery of itself and what it lacks. This definitive collection, edited by one of the world’s pre-eminent authorities on populism, Francisco Panizza, combines theoretical essays with a number of specially commissioned case studies on populist politics in the US, Britain, Canada, eastern Europe, Palestine, Latin America and South Africa. A broadly shared understanding of the nature of populism gives the book a coherence rarely found in collective works and enhances the richness of the case studies.
