My works fall within the contemporary tendency which values the legal aspect of the social sphere as a fundamental element for the understanding of the mechanisms of contradiction and conflict which characterize it. However, the reality we grasp via the law is instantaneous, static, frozen at a certain point in time. Therefore, a diachronic analysis of the economic, political, institutional and demographic context in which laws originate must be contemplated as well. That's why I consider the historical framework as adequate for understanding the legal dimension of the social. With this objective in mind, I used the developmental strategy concept, to be understood as the ensemble of essentially public actions the dominating group in the state apparatus proposed to the rest of society in order to impose their social model1 (1).
