Recently an English nationalist told me that he would be sad if Cornwall separated from England (Please note! England not UK!) as he had always considered it part of his country [England] and that he had spent many happy childhood holidays there.
For the first point we had to agree to disagree but for the second, at the time, I simply accepted his view and conceded his potential regret if Cornwall left England. It's only later I asked my self, 'why would it change the way he viewed his childhood vacations in Kernow?' More generally, would it dissuade English tourists from visiting the Duchy? Does Wales being separate from England stop English people going there and having a fine time? Why should Cornwall be any different?
If Cornwall were rightfully recognised as one of the home-nations, in line with its culture and constitution, would it dramatically reduce the number of tourists it gets? I think not. In fact, quite the opposite could be true.
Cornwall already has a reputation far larger than any English county. Most of the major, and many of the minor, European languages have specific words for Cornwall and the Cornish. Europe's cultures recognises the South West peninsula of Britain as the 'Cornish peninsula'. The Arthurian legends, including the tragedy of Tristan and Isolde popularised by Wagner, are world famous. The transnational nature of the Cornish identity -the diaspora in Australia, America, South Africa, Mexico- also ensures that Cornwall is simply bursting out of the English county box. Giving it greater recognition would simply increase its international profile and, not only attract more tourists, but help sell Cornish produce too.
Anyway, the event advertised above and organised by the very promising Bewnans Kernow is the place to learn more about how the Cornish identity could help Cornish business. One not to miss!
