The origins of Britain stretch back to before the Roman period. By the time of the Roman conquest, the culture of Britain had around fifteen hundred to two thousand years of development behind it. ‘The Beginnings of British History’ looks at the distinction between the Roman period for Britain and what happened before. There is some truth to the assertion that the study of Roman Britain is prehistory, in that we need to lean on archaeology as a main source of evidence. The critical difference between Roman Britain and what went before, however, is that society before the Romans was literate. Roman Britain was also a world dominated by the rule of law.
