This work aims to vindicate the figure of president Francisco I. Madero before the terrible defamation of his image in revolutionary Mexico. Barajas offers us an account of the process of deformation suffered by the revolutionary caudillos in the press as a counterrevolutionary method on the part of the Porfirist elites. The work is divided into nine chapters that address various themes and characters that contextualize the figure of Madero and explain how and why he was highly criticized in the cartoons of the time. The work speaks of the responsibility of journalistic work as a content creator. Barajas invites reflection on the enormous power of journalism when it is time to build public opinion.
