In 55 and 54 BC, Julius Caesar, as part of his campaigns in Gaul, invaded Britain and claimed to have scored a number of victories, but he never penetrated further than Hertfordshire and could not establish a province. However, his invasions mark a turning-point in British history. Control of trade, the flow of resources and prestige goods, became ever more important to the elites of Southern Britain; Rome steadily became the biggest player in all their dealings, as the provider of great wealth and patronage. A full-scale invasion and annexation was inevitable, in retrospect.
