Correlations
There is nothing known to connect the word 'Lloegyr' with any political or social entity earlier than the Middle Ages, nor can it be said to be the medieval Welsh name for an earlier political or social entity.
However, its boundaries agree quite well with limits of the Romanised part of Roman Britain. Inside those boundaries was a heritage of Romano-British society, laws, and customs that had evolved in the 350 years of Roman rule. Outside of those boundaries Roman rule was largely a matter of coexistence with the Roman military, without the same Roman contribution to local society, politics, laws, and customs. At the end of Roman rule, there were two societies with different histories, customs, and laws, which is not to suggest any substantial difference in cultural mores.
