It is important to encourage the idea of the necessary historical closeness of state law and civil law: the so called constitutionalization of private law is not new, especially from an interdependent and epistemological level of their application. In many other eras, they could be analyzed, dealt with placing lies about the revival of the law in the West, not only because in feeling that the prevailing dogma, is a decisive legal moment in many aspects, but rather because it is considered that a simple descriptive approach of these events can generate, among other effects, better apprehensions of legal doctrine in the students and enable a better understanding of subsequent historical development. The text figuratively exposes the concern that in the eleventh century was by political legitimacy, which is mutated due to the new enthronement of the law, likewise critically describing the academic, cultural, economic and of course epistemic revolutions that allowed for there discovery and Resettlement of Roman law in the era. The importance of collective reflection on the law, which can work to over come times of great conflict is explored, which is valuable for the current Colombian context. The text does not intend to make historical corrections.Abogado y magister de la Universidad Nacional de Colombia, Magister Llegum (Ll.M) y Doktor Iuris (Dr. Jrs) de la Universidad de Konstanz, en el Estado de Baden Württemberg, en la República Federal de Alemania, Rigurosum en a) Derechos Fundamentales, b) Historia del Derecho y c) Derecho Civil, como área nuclear.
