Unlike other historical works, which have suggested that the national abandonment of revolutionary reform was due largely to corruption, this work reveals that often corruption had little to do with it; rather, old cultural beliefs worked their way to the surface within individuals. This biographical work takes scholars of modern Mexico from the late nineteenth-century dictatorship of Porfirio Diaz to the eve of the massacre at Tlatelolco on 2 October 1968, when the so-called 'Revolutionary' government murdered several hundred students in Mexico City's Plaza de las Tres Culturas. This book reveals the increasingly conservative bent of a particular revolutionary, in the person of Antonio Diaz Soto y Gama. He fought for agrarian reform by serving under Emiliano Zapata as a secretary and intellectual advisor during the Mexican Revolution (1910-1919). Diaz Soto y Gama shifted from Marxist anarcho-syndicalism and anticlericalism to ultraconservatism and devout Roman Catholicism within less than thirty years. Rather than an anomaly, he was typical of many former leftists who espoused fascism just before World War II and anticommunism during the Cold War.Such deep-seated convictions affected the way these persons - many of whom were articulate and enjoyed national renown - saw the world, Mexico, and themselves.
