I have not got time right now to pursue this further.
But until we can get accurate estimates of the population at the end of the Roman times, from land use and other studies, it would not be possible to produce an accurate model of what could have happened?
Is there a reference for this? Surely, somebody has looked into this?
If the population levels are much lower than some people have estimated, the Roman occupation could have more profound affects on language change as well.
Hypothetical.An attempt to refine the population model so it would fit in with the linguistic theory:
Immigrant Population doubled every century = 16,000
Native population reduced by one third in the same period = 13,000(round down from 13,333)
Proportion of Germans =over 50% = enough? for a language change according to
the linguists theory. The linguists really want 70% majority if words are not be carried from the old language (Brythonic) into the new Old English. The actual percentage is 55% to 45%.
The percentages would then be German 53%, Brythonic 30%, Latin 17%. So the non-Brythonic (first language) speakers would be 70%.
Estimated population of
(These figures have not been double-checked)
Although I started off being sceptical that the Germans would not be numerous enough to replace the Brythonic language when this proposal was suggested to me, it is possible that this could have happened.
My original was thinking was that post Roman Britain was bi-lingual and I think if anything the various views and thinking have strengthened this view.
If the population in
It is easy to get muddled up with figures. By increasing the number of immigrants it is well possible to make the linguistic model nearly work (which was not what I thought at first!).
What does not seem to have happened is that the Germans got assimilated into the native population as some historians say. It was a political takeover involving violence and replacement. But I would say there greatest success could have been breeding. Having displaced the locals of the best land, they became a more biologically successful group (especially the males).
I think I made a mistake with the previous model because
it was not sophisticated to allow for spread, the snowball effect, inasmuch
the immigrants would have settled the east, south coasts and
So if I was divide
My conclusion:In 200 years the German immigrants (maybe only 10%) transformed a bi-lingual Romano-Brit culture with Celtics into the English culture. The principal method was displacement and occupation of the best lands requiring force. Their success could be because of their greater biological success than the natives.
This is speculative; the experts in population studies must have got this down to an art form. I have not read the books though.
