Ædui

, or Hedui , a powerful nation of Celtic Gaul, known for their valour in the wars of Cæsar. When their country was invaded by this celebrated general, they were at the head of a faction in opposition to the Sequani and their partisans, and they had established their superiority in frequent battles. To support their cause, however, the Sequani obtained the a istance of Ariovistus king of Germany, and soon defeated their opponents. The arrival of Cæsar changed the face of affairs; the Ædui were restored to the sovereignty of the country, and the artful Roman, by employing one faction against the other, was enabled to conquer them all, though the insurrection of Ambiorix, and that more powerfully supported by Vercingetorix, shook for a while the dominion of Rome in Gaul, and checked the career of the conqueror.
