Ambiorix was, together with Cativolcus, prince of the Eburones, leader of a Belgic tribe of north-eastern Gaul, where modern Belgium is located. In the nineteenth century Ambiorix became a Belgian national hero because of his resistance against Julius Caesar, as written in Caesar's Commentarii de Bello Gallico.

The Eburones were a Gaulish-Germanic tribe dwelling in the northeast of Gaul, who lived north of the Ardennes in the region near that is now the southern Netherlands, eastern Belgium and the German Rhineland, in the period immediately preceding the Roman conquest of the region. Though living in Gaul, they were also described as being both Belgae and Germani.
