Two of the largest exports to Gaul from the Roman Republic, and later Empire, were wine and olives. Although some tribes eschewed luxuries, such as the Spartan-like Nervii, the majority of Gauls and Germans prized Roman goods. Exorbitant fees were paid for every vessel and barrel that enterprising traders brought across the Alps. In exchange they received gold, silver, or slaves in payment, all of which fetched high prices in the markets of the Republic. Through granting concessions on trade, Caesar was able to offer great profit to his supporters.
