Kingdom of the Regni

43 CE – 80 CE (approx.) · capital Noviomagus Reginorum (Chichester)

Client kingdom of Togidubnus in Sussex and Hampshire, a loyal ally of Rome after the conquest whose seat may have been the palace at Fishbourne.

Origins

After the Roman invasion of 43, much of the former realm of the Atrebates (Britain) was entrusted to Togidubnus, a British noble loyal to Rome. Tacitus says that certain states were given to him and that he remained faithful down to his own day, and the region became a base for Roman operations along the south coast.

Rule and society

An inscription from Chichester dedicating a temple to Neptune and Minerva names Tiberius Claudius Togidubnus as great king in Britain, showing that he held Roman citizenship and royal status. His capital, Noviomagus Reginorum, grew into a Roman-style town, and the lavish villa at Fishbourne, with mosaics and formal gardens, has often been linked to him. The kingdom provided Rome with a stable and Romanised territory.

Decline and legacy

When Togidubnus died, probably around 80, the client kingdom was absorbed into the province of Roman Britain. Its lands were divided into civitates, the Regni around Chichester and probably the Belgae (Britain) around Winchester. Chichester remains the main town of the region.
