In this book, Carlos Illades summons important intellectuals to reflect on communism in Mexico. The authors provide a high-quality analysis of the left-wing organization all over the country in the 20th century -in its historical, cultural and political dimension-, inscribed in an international political scenario where communism sought to transgress the borders of the Soviet countries. Specialists from different countries and generations are given the task to delve into these pages the intellectual dimension of the Mexican Communist Party, its rise and decline; the significance of the editorial sphere and emblematic figures such as Wenceslao Roces or Vicente Lombardo Toledano; the influence of communism in popular culture in the 20th century in Mexico, among other topics.
