In the process of awareness of the objective reality arise certain concepts through which man fixate and express the proprieties, characteristics and links of the objects and phenomena’s of the outside world. The concepts that reflect the most important aspects, links and or characteristics of a field of phenomena’s constitute its categories. Each science possesses its own categories. In the case of the field of Theory of underdevelopment its categories arise during the first postwar period. After the Second World War, in publications of the United Nations began the utilization of the category underdeveloped to designate the specific-historical reality of the peripheral countries linked to the capitalist system. It was expressed, with this category, the set of properties, characteristics, links and relationships, generally-essential and specific, of the new phenomena that reached in the process of its evolution the point of its full maturity. It was the way, to say it in a different manner, that the thought was taking ownership of this new historical reality. To such a point did society become aware of the underdevelopment that innumerable dependencies arose state, international, academically and university wide by those overseeing the phenomenon.
