The following article deals with the brief history of the Constituent Assembly of Workers and Intellectuals or " Small Constituent" that took place in Santiago de Chile between March 8th and 11th, 1925, days before the constituent process announced by the government took place. Said deliberation, driven by the initiative of a wide variety of organizations of the Popular Movement (Communist Party, Federation of Chilean Workers, General Association of Teachers, Union of Chilean Employees, Federation of Chilean Students, anarchist sectors, democrats, radicals and feminists, among others) came promptly to an end due to the imposition of the official constituent itinerary of president Arturo Alessandri Palma. In a similar fashion, the promoters of the "Small Constituent" erased the experience from their collective memory, paving the way for its silencing or minimization by historians that specialize in said period of time. Recently, contrary to forgetting and minimizing, this reflection lead by organized popular sectors has been presented in a mythified fashion as a constituent power exercise of completely autonomous "social bases", without any link to the political models present in the Popular Movement. Facing both opposite ends that show up in the collective memory and in historiography, the author of this article reconstructs the context in which the Constituent Assembly of Workers and Intellectuals sprang forth, its conception, development and outcome, to bring us closer, based on a wide variety of sources, to a more balanced and objective point of view, that is to say, closer to the historic truth.
