actually we have been declared an official and recognised minority now. bear in mind that historically we had our own currency, parliament and language and are part of the original celtic nations within this island. We're capable of a bit more than a cream tea to the odd tourist.
Despite my surname, one of my great-grandmothers from Fowey went to Devonport to work and met/married a shipwright from Gloucester and they then moved back to Cornwall, almost all of my family on both sides are Cornish and I have always taken an interest in our origins.
At least 15 years ago I read an article based on DNA research concerning the origins of the Cornish and this showed that we are different from the other Celtic races, Welsh, Irish and Scottish, within the UK, apparently our closest relatives are the Bretons and Portuguese. The article also said that the original people who became the Cornish migrated from the Middle East around 4,500 years ago. This could explain why most of us get brown very quickly when sunbathing

.
In the 1990's and before I had read the article, I had a holiday on the Algarve and on seeing the older people in the inland villages I was struck by the fact that they looked very much like the older generations of Cornish people that I knew when I was a child. I have since been to Brittany and again the older Bretons look very similar to us, obviously, just as with the Cornish, this has changed during the last 100 years due to the much greater freedom of movement that has been possible for the ordinary people in each country.

Such as hard rock mining, inventing the first really practical steam engine and fighting the English like this during the Civil War.
The Cornish had given so much to the Royalist cause during the Civil War that they were exhausted. After overcoming the English at Stratton, the Cornish regiments had marched eastwards to capture Taunton, Bridgwater, and Bath. They had figured prominently in the taking of Bristol, but their losses had been severe, especially among their leaders. The Cornish Army's loyalty had been to its leaders, and not to the English commanders who now exerted authority. The survivors of the Cornish regiments headed home. Although depleted in numbers, they yet managed to overcome Dorchester, Weymouth, Portland, Bideford, Barnstaple, Exeter, and Dartmouth. Almost single-handed, the Cornish had taken on the rest of the South West counties and won many famous battles. (
Feats later to be emulated on the rugby field!)
