Dobunni - Authority in Tribe from ? to 96 AD
The Dobunni were one of the Iron Age tribes living in the British Isles prior to the Roman invasion of Britain. There are seven known references to the tribe in Roman histories and inscriptions.

The tribe lived in the part of southwestern Britain that today broadly coincides with the English counties of Bristol, Gloucestershire and the north of Somerset, although at times their territory may have extended into parts of what are now Herefordshire, Oxfordshire, Wiltshire, Worcestershire, and Warwickshire. Their capital acquired the Roman name of Corinium Dobunnorum, which is today known as Cirencester.

Unlike the Silures, their neighbours in what later became 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.

Even though the Dobunni were incorporated into the Roman Empire in AD 43, their territory was probably not formed into Roman political units until AD 96-98.
