Aedui, a highly developed Celtic people who occupied most of modern Burgundy. They appealed to Rome against the Arverni and Allobroges (121 bce) and received the title of fratres consanguineique. During the Gallic War they gave valuable though not whole-hearted support to Caesar, and when they finally joined Vercingetorix in 52 bce their support was lukewarm. Under the empire, though involved in the revolts of Iulius Sacrovir (21 ce) and Vindex (68), their aristocracy became highly Romanized. The hill-fort Bibracte was abandoned for Augustodunum; duoviri replaced the vergobretus as magistrates; and, under Claudius, the Aedui were the first northern Gallic nation to furnish Roman senators.
