stocked large quantities of cereals and wine imported from the southern countries have been found. One of these wooden cellars has recently been reconstructed. Without a doubt, it was in these buildings that the Aedui centralized their harvests and imports. Politics The political system of the Aedui was essentially reformed according to indications in the Commentaries on the Gallic War. At the head of the Aedui state sat a senate comprising one member of each Aedui aristocratic family. What is today called executive power was held by the vergobret, the supreme magistrate, who exercised his functions over the course of a year. He was forbidden from leaving the borders of the territory during this period, which prevented him from commanding the army outside the borders. This measure, along with that which authorized only one voice per aristocratic family in the senate, aimed to prevent any individual or their family from monopolizing the reins of power. The vergobret was publicly elected by a council directed by the druids. Among the Aedui, it seems like the vergobret also exercised a judiciary role, since Caesar reports that he had "the right to life and death over his fellow citizens". Finally, it is thought that the vergobret was responsible for the administration of the territory. Caesar adds that the druids were charged with this: "They believe that religion does not allow them to put the material of their education in writing, while for the rest in general, for public and private administrative acts, they used the Greek alphabet." No excavation has permitted the rediscovery of such acts, the backings of which, being wood covered with wax, are perishable. Furthermore, it is known that the druids held high functions since Diviciacus came to Rome to plead the case of the Aedui during the Germanic invasion led by Ariovistus on the account of the Sequani; he also directed the Aedui cavalry during the Gallic War after the death of his brother Dumnorix. Therefore, it is thought that some druids held high military positions. Archeological research on Mont Beuvray From 1865 to 1895, Gabriel Bulliot identified Bibracte in 1867 and began excavations there (notably the Celtic artisanal neighborhood surrounding the Rebout gate), with the aid of funds allocated by Napoleon III. In fact, having a passion for history, the emperor set off vast campaigns of excavations to uncover sites of the Gallic War in order to write
