Fucking hell, 'Wales' hasn't existed as a real country, separate from England, for nearly 500 years officially. Owan Glyndwr was the last man to lead a seperate Wales, and that was in the early part of the 15th century for christs sake. The Welsh 'celtic' identity is just a mish mash of other cultures they've cobbled together to sell to tourists.
What would the national anthem be if not the British one? Bread of Heaven?
I should add I like the Welsh, lived in Swansea for years. Just seems a bit thick. Then again, Newport is Newport...
Actually I think it's probably a lot longer than that. Late 13th century I think. But in that case you have to also admit that in the same way England hasn't existed as a country since the act of the union in the early 18th century.
And for an Englishman to moan about another nations culture being a "mish mash of other cultures ... cobbled together" is perhaps the most ironic thing I've ever read. England - The language has French / Latin / Germanic and Norse roots, the exact proportions of which vary from region to region. The patron saint is Greek / Palestinian, the motto is French, the flag borrowed from the crusaders and / or that adopted patron saint. There's a definite pot / kettle thing going on here.
