Roman organization and laws were like an oasis in the desert of the known world map. It was not surprising that the British suffered both physically and from a certain degree of culture shock after the Saxon arrival. Longer Than The Romans hat we should not forget is that the Saxon age lasted for six hundred and fifty years. In fact, right up until the Battle of Hastings in 1066. This was longer than the Roman occupation.
Many historians consider the Roman occupation as subjugation of the population.
Rome tended to have the last word and it was unwise to voice an opinion or rise against her. The Pagan's of Anglesey being a case in point. The lifestyle of the average Briton was proportionate to his status. It is still a matter of modern conjecture as to what age was preferable. Slavery was endemic for those unlucky enough to be born into the lower classes during Roman times.
