This paper advances the thesis that democratic populism and the commons can and should complement each other in counter-hegemonic interventions promoting egalitarian and ecological democracy in our times. After elucidating its key terms, the article makes, first, a theoretical case for the combination of egalitarian, inclusionary populism and the commons by debunking arguments which highlight the conflicts between them and by explaining the political significance of their conjugation. Subsequently, discussion builds an empirical argument for the real possibility and the democratic promises of such a convergence by considering three ways in which populist politics and the commons merge and recompose each other in contemporary social movements, from the Spanish 15M and new municipalism to Occupy and other collective contestation in the Americas over the last two decades. These cases will illustrate how late social activism has effectively blended populist mobilization with the spirit of the commons, engendering a hybrid figure of ‘common populism’ that fosters grassroots processes of democratization.
