main objective in this article is to describe how, through the application of the Conflict Curve of Lund, the migratory process of Venezuelans to Colombia can be explained between 2012 and 2017, which outlines from an analytical perception how A conflict can be resolved or de-escalated from the implementation of a preventive diplomacy. For this, the most relevant or historical events in Venezuela are taken into account from 1998 to 2017. Subsequently, the relationship between the internal conflict in Venezuela and bilateral relations with the Republic of Colombia between 2007 is described. at 2017. theory of Lund was chosen, and its tool called The Conflict Curve, which represents a graph that illustrates the different behaviors of a conflict and verifies if the actions carried out by the different actors were the most effective and correct to mitigate that the risk escalate to an even greater conflict. This theory implies several structural elements namely: (i) the five stages or states of the conflict; (ii) the priority tasks and; (iii) the tools to face a problem and how to solve it from the Preventive Diplomacy, which is the main point highlighted by Lund in his book Prevention of Violent Conflicts - A Strategy for Preventive Diplomacy Under this analysis was established since Hugo Rafael Chavez Frias assumes the presidency of Venezuela, socio-political changes were generated that shaped the socialism of the XXI century. Once the Venezuelan head of state died, under the government of Nicolas Maduro, the internal problems of Venezuela increase the increase in unemployment, hunger, forced displacement, among others, which are reflected in the handling of international relations towards Colombia, with measures such as massive deportations of Colombians, and likewise it has a directly proportional impact on the magnitude of the migratory flow of Venezuelans to Colombia. It is important to specify that the scope of the study is not theoretical but methodological, since it is structured from the application of the Conflict Curve of Lund as a methodological tool, which is based on the author's theory used as a reference. Therefore, it is not intended to support or controvert the theory but to apply the Curve proposed by the author to both internal and international conflicts linked to migratory processes, in order to describe and explain them.
