Historiography realized that the Middle Ages were not the “dark agesâ€ of the European civilization. On the contrary, the period generated a series of ideas and phenomena that are associated with the modern period. At the beginning, the first chiefs of states started by establishing connections with the church authority (through the rituals of crowning, anointing, or through the magic powers attributed to the king’s touch). Gradually, and due to the contribution of some important thinkers (such as Thoma d’Aquino, Dante or Marsilio di Padova), the fundaments of the rational concept of the state organization were settled, in the transition period of the XIIIth- XIVth centuries. The author discusses these ideas (of the natural rights, of the conciliar doctrine) underlining their importance in the formation of the modern paradigm.
