Dio Cassius referred to the tribe as "Bodunni", probably a misspelling of the Dobunni. Tributary to the Catuvellauni, they capitulated to the invading Romans when
Caratacus and
Togodumnus withdrew. Unlike the
Silures, their neighbours in what later became southeast
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. The tribal territory was divided into a
civitas centred on Cirencester, and the
Colonia at Gloucester. The
Colonia was established during the reign of the emperor Nerva (AD 96–98). At the beginning of the 4th century, Britain was reorganised into, initially, four and then five provinces. The Dobunnic territory lay in the province of Britannia Prima, as described in an inscription found at the base of a
Jupiter column. The area remained a Roman
civitas until approximately 409. The Dobunnic territory contained two large towns (Corinium Dobunnorum now Cirencester, and Colonia Nerviana Glevum now Gloucester). Besides this there were numerous smaller towns, and many rich villas. Stephen Yeates asserts that a study of the religion of the Dobunni has shown that there was a focus on the worship of the natural world. It is possible to identify deities associated with the landscape, for example *Cuda, a mother goddess associated with the Cotswold Hills and its rivers and springs, and Sulis Minerva at Bath. Other cults were defined by social action, such as mining, for example at Lydney Park, and hunting, for example at Pagan's Hill near Chew Stoke. ==Sub-Roman period==
