The objective of this work is to show the relationship between the rule of law and crises. The Legislative State of Law will emerge from the crisis of the absolutist model, the English, American, French revolutions and the independence processes of Latin America will allow its consolidation. In other crisis, that arouse from the Second World War, many states assumed the constitutional model of Law. With an analytical-descriptive methodology, it was possible to conclude that, in the face of the greatest health crisis of the last 100 years in the world, generated by the covid-19 pandemic and the use and abuse of states of exception by states to face this crisis, the Inter-American Human Rights System will be one of the calls to preserve the rule of law, consolidating what some have called the Conventional State of Rights. © 2020, Universidad del Zulia.
