There' s no Roman newspaper morgue, or archive of reports from the legions, but the surviving information shows that the most habitable and pleasant parts of Britain were conquered straight away, and the dumps (Caledonia for instance) were not bothered with. Britain was a popular place to live and the locals adopted a number of Roman cultural norms. The economy boomed and traded by sea even into Byzantine times, it remained remote from tumults on the continent, and the supposed revolts were short-lived and quickly eliminated and forgotten. Literally the only evidence Boudicca ever lived is found in a Roman account. Modern nationalism among Europeans has included looky-heres to exaggerated ancient resistance that not only was brief and clearly unpopular, but involved earlier coats of paint that the current locals' ancestors superseded.
