How (culturally, linguistically, religiously) diverse could Britain be prior to the immigration era?
POD must be after 400.
That would be less diverse I'd think, seeing as the remaining Brythonic tongues would probably be mutually intelligible with each other and all the peoples in 'England' would have a similar culture.The native Britons don't assimilate. The Picts and some of the other Gaelic kingdoms stay and keep fighting each other.
you do realise most of these groups are immigrants.
Also - A far as London is concerned ( i think it applies to all the major port cities) its only by the 1980/90 that we approached the level of ethnic diversity that existed in the late 18th early 19th century.
How (culturally, linguistically, religiously) diverse could Britain be prior to the immigration era?
post-WWII, when it became possible for Bangladeshis, Indians, Turks, Poles, etc. to settle in Britain. Obviously, getting a diverse Britain is too easy then.Still not sure what you mean by the immigration era when referring to England. Do you mean before 1890's when significant number of Italians and Chinese joined the Irish and Jews that had lived in England for a couple of centruies.
Or do you mean the various invasions of people from the continant from 49AD to 1066AD?
