Roman Coins and the Roman Empire

There were about 20 major celtic tribes in britain, and rome had entered into alliances with some of those tribes. Roman coins were being minted by this point in and around modern belgium which was part of the northernmost region of roman gaul. These coins were payment for british goods like cattle, grain, tin, iron, hunting dogs and even slaves. Rome also traded roman luxury goods for those items, including wine and olive oil. But trade and political alliances were not enough for emperor claudius. He needed a new territory to conquer, and britain would serve that purpose very well.
