In this timeline, we do not claim to cover the entire history of Guerrero, but instead intend to give some key elements that may facilitate a better understanding of recent developments. Since the 1960s, the state of Guerrero has been characterized by high indexes of poverty, social disintegration, organized crime, corruption, repression and impunity. During this time, the state of law was constantly violated and state crimes were committed that have still not been punished. We decided to take this watershed moment of the 1960s and the so-called “Dirty War” as a starting point to this chronology. In it, we will focus on the main problems, consequences and responses by the population throughout time.
