I found this absolutely fascinating. I’ve always loved maps, and this is the first time I’ve found a succession of maps showing the differing tribes of the isles throughout time in such a clear progression. At the bottom are some good information about DNA migration, as well.
Remarkable DNA study shows modern Britons still live in same tribal kingdoms as their ancestors in 600 AD. New maps show Celt, Roman, Anglo-Saxon and Viking territories in British Isles.
