ENGLISH DESCRIPTION It's undeniable that Lazaro Cardenas marked a breaking point in Mexico's history, but that does not exempt him from controversies as president. Was his government more bourgeois than socialist? Was he really a leftist revolutionary president or was it just a farce? Did "Cardenalism" really denote a radical change in the way of doing politics in Mexico, or was it just a continuation of the same? In order to understand the Mexico of today, should we first try to understand Lazaro Cardenas? "Since politics often times distort history, and what we know about Lazaro Cardenas has more to do with the narrative of each current president than with actual historical facts, this volume of Heads or Tails is presented by two young historians who dove into research of this historical figure to present their own interpretations to the readers. "History is not set in stone, it is dynamic and is constantly being interpreted. From a perspective that seeks to shed light on the facts and bring them to a broad audience, Veka and Francisco take readers to meet a personality and a moment in history that defined the political system that is still in place today." -Alejandro Rosas
