Abstract
The lecture begins with an evocation of its " situation " in the course of the lectures (courses and seminars) since 2016 by returning to the euristic value of the notion of experience. Here, we consider it in its relationship toagency, according to a historical dialectic thought up by Edward Thompson (" Men act, experience, think and act again "). But from what past ? Between the Greco-Roman reference past (whose historical anthropology enables us to distinguish between politics and policy ) and the " more current past " of the Enlightenment, we question the theoretical effectiveness of the medieval past. This is based on a case study : Ernst Kantorowicz's analysis of the liturgical acclamations of the royal cult, a seemingly out-of-date object which, at the time he wrote his book(Laudes Regiae. Une étude des acclamations liturgiques et du culte souverain au Moyen Âge, 1946, trans. fr., Paris, 2004) a noisy political topicality, forcing the historian to question " the dangers inherent in the profession of exhuming the past ". The analysis we propose, based on a re-reading of this scholarly investigation, focuses on the liturgical genesis of modern government. It also makes it possible to carve out a past available in the medieval period, very broadly : from the Carolingian knotting in the years 780 between Davidic kingship and liturgization of secular power to the three possible ends of royal praise (with Richard II in 1377, with Charles V in 1530, with Charles of Habsburg in 1918), which also represent three possible ends for the Middle Ages.
