Aedui, Or Hedui, a powerful people of Celtic Gaul, between the Saone and the upper Loire, which rivers separated their territory from the countries of the Sequani and Biturrges. They were the first Gallic tribes which concluded an alliance with the Romans, and having, after a struggle with the Sequani, fallen under the power of Ariovistus, the German ally of the latter, were restored to power by Julius Caesar, shortly after the opening of his Gallic campaigns (58 B. C.). They joined, however, in the great rising against that conqueror under Vercingetorix (52), on whose fall they were leniently treated by the victor. Their chief town was Bibracte, subsequently called Augustodu-num, now Autun, in Burgundy.
