 Caesar treated them as a distinct people from the "Germani" although their ancestry was also in the east, because they were descended from remnants of the Cimbri.Because they had a fort on large hill, and their name may even mean "fort people" it is thought that the Aduatuci lived in hilly Wallonia, possibly near Namur.Ambiorix, one of the two kings of the Eburones, complained to Caesar that he had to pay tribute to the Aduatuci, and that his own son and nephew were kept as captive slaves by them.
