Cornwall has a relatively strong regional identity, but no more so than loads of other places in England. The only thing that's really unique about it is that people carried on speaking a Brythonic language there for longer than the rest of England, before it died out in the 1700s. In the 19th century there was an effort to revive the Cornish language and create a Cornish nationalist movement, but it hasn't exactly been successful. Iirc there are like 5 native Cornish speakers nowadays, and the nationalist party Mebyon Kernow currently control 3% of the seats on the local council (they're tied with Labour lol). They're no more "indigenous" than anyone else is - that word doesn't really make sense in most of Europe and is mostly used by racists.
That's not a thing.
