This formative course provides first-year students with a better understanding of legal concepts through their historical analysis within the framework of various and successive political models. Although they are grounded in Western legal tradition, these concepts were reformulated by the Enlightenment and the Liberal Revolution and have acquired today (following the crisis of the liberal system and the triumph of the constitutional and democratic state) a whole new meaning. Only by becoming aware of this historical depth can students understand and value the conceptual tools they will employ in a globalized and changing legal order. In this course, students will learn about the evolution of the legal system, its institutions, and the legal-political doctrines. This way, they will discover the social value of the law, acquire a critical sense of its evolution, and develop their ability to synthesize information. In short, it will provide students with interpretive elements that will allow them to take ownership of their professional future instead of simply being the recipients of facts.
