History
Founded in Mexico City on May 5, 1989 by Cuauhtémoc Cárdenas, Heberto Castillo, Marco Rascon Cordova, Gilberto Rincón Gallardo, Porfirio Muñoz Ledo, other prominent PRI members and left-wing politicians. The party was originally founded by including many smaller left-wing parties such as the Partido Comunista Mexicano (PCM, Mexican Communist Party), Partido Socialista Unificado de México (PSUM, Unified Socialist Party of Mexico), Partido Mexicano Socialista (PMS, Socialist Mexican Party) and Partido Mexicano de los Trabajadores (PMT, Mexican Workers' Party). The PMS donated its registration with the Federal Electoral Commission (CFE) to enable the new party to be established.

It was proclaimed to be the party of the 6 de julio (July 6), referring to the date of the 1988 presidential election where it is alleged that Cárdenas, the candidate of a coalition of center-left parties called National Democratic Front (Frente Democrático Nacional) won the election but was denied victory by fraudulent means. Victory was instead handed to PRI candidate, Carlos Salinas.
