The development of the Roman provinces in Britain (1st cent. AD – AD 410)
The Romans first crossed the Oceanus Britannicus in 55 and 54 BC under Caesar when he was proconsul of Gaul (see Map Caesar’s proconsulship in Gaul (58 – 50 BC)). Since then Rome had maintained its claim of dominion over the island, but this claim had never been realized in the form of a Roman provincial administration. The islanders had merely been obliged since to pay import and export duties. Plans to subjugate the island, prepared under Augustus, Tiberius and Caligula, would only be implemented under Claudius (AD 41–54).
