At the National Archives in Paris, Bruno Solo reopens with emotion the will of King Louis XIV. This document, written on August 2, 1714, while the sovereign was ill, caused tremors throughout Europe on the day after his death. Louis XV, being only 5 years old, who will govern in his name? Philippe II, Duke of Orleans, the nephew of the deceased king, was in charge of the Regency for seven years. During this period, the alliances in Europe are upset, the morals of the French are liberated. The Regent tried to re-establish the economy and trained Louis XV to one day rule his kingdom.
