People's democracy was a theoretical concept within Marxism–Leninism (and a form of government in communist states) which developed after World War II, which allowed in theory for a multi-class, multi-party democracy on the pathway to socialism. Prior to the rise of Fascism, Communist Parties had called for Soviet Republics to be implemented throughout the world, such as the Chinese Soviet Republic or William Z. Foster's book Towards Soviet America. However, after the rise of fascism, and the creation of the Popular Front governments in France and Spain, the Comintern under Bulgarian Communist leader Georgi Dimitrov began to advocate for a broad multi-class united front as opposed to the pure proletarian dictatorship of the Soviets. The possibility of a trans-class democracy was first put forward during the Popular front period against Fascism.
