Resumo. This work aims to show the historical synopsis of the sentence, as well as its theories, as a purpose, regarding the prison and the reality of the Brazilian prison system. For this, the empirical and deductive approach methods, monographic procedure method and bibliographic, academic and documentary research were adopted. The situation of Brazilian prisons is critical, as it is marked by overcrowding and constant violations of human rights, as well as the lack of minimum conditions for serving the sentence in a dignified manner, where the process of re-socialization of the prisoner does not exist, and the rates recidivism are alarming, characterizing a deep bankruptcy of the prison and penal system, where the results are the increasing increase in violence, crime and the feeling of insecurity experienced by the whole society. Even though society has evolved a lot, social problems are still present. Most Criminal Organizations are installed on the outskirts of the city, where humble people and very low quality of life are found. Places like these are in need of state aid, which also happens to the rest of the population without any discrimination. Otherwise, these criminal organizations or factions are installed within the prison system, promoting riots and rebellions, turning into major crises that must be managed by the prison system. The study of Crisis Management, as in any other branch of scientific knowledge, there is a need to establish certain basic principles and definitions for greater doctrinal uniformity.
