The Regnenses tribe inhabited East Sussex, West Sussex and parts of Surrey and Hampshire. They were seemingly an amalgamation of Belgic peoples gathered together under the client king Cogidubnus by the Romans. The Kingdom did not exist prior to Roman rule.
Another passage in Ptolemy Book II Chapter 2 gives the ancient name of one other geographical feature within the territories of the Regnenses tribe:
The civitas capital of the Regni and the probable seat of king Cogidubnus, who was styled Rex Britannorum 'King of Britain', also Legatus Augusti 'legate of the emperor'.
The most extensive industry in the canton were the iron workings of the Weald of Sussex. Other Iron workings near the south coast came under the jurisdiction of the Cantiaci in Kent. A brick and tile factory existed at Ashtead in Surrey. A number of villas appeared on the southern coast in the second century, with dependant farms apparently sited on the downs inland. Several other villa groups have been noted along the North Downs Trackway, and a third group centred on Pulborough and Hardham includes the very large villa estates of Bignor and Borough Farm. Rural temples have been identified at Farley Heath in Surrey, and in Sussex at Chanctonbury Ring and Lancing Down.
|Cogidumnus||King of the Regnenses of West Sussex, became a client king of Rome, taking the name Tiberius Claudius Cogidumnus. Possibly a relation of the Atrebatean noble Verica, who assisted Claudius during the invasion of 43AD and feasibly recommended him to Rome as his heir.|
