The Dobunni were a large group of farmers and craftsmen, living in small villages concentrated in fertile valleys. They were one of the few tribes known to issue coins before Roman arrival and the introduction and adoption of Roman currency. Unlike the Silures, their neighbours in south east Wales, they were not a warlike people and submitted to the Romans even before they reached their lands. Afterwards they readily adopted the Romano-British lifestyle.
Numismatic evidence suggests that the Dobunni kings subdivided their land between a north and south zone, sometimes becoming unified in a single ruler.
