Albion is usually regarded as geographically equivalent to Britain - that is, England, Scotland, Wales and the nearby islands. But what about Ireland? Are the British Isles a spiritual group of distinct but inextricably-related nations; or is Ireland a separate place altogether, with a separate destiny from the mainland?
I can see reason on both sides; but - in a world perspective - I suspect that the British Isles are supposed to be a distinct spiritual entity, with especially strong inter-relations. Certainly, antagonism between Ireland and Britain is a deeply damaging state of affairs on both sides.
Ireland is more distinct than any of the other three. For example, Wales hasn't ever quite been a nation - and Cornwall and Cumbria (in England) have distinct Welsh aspects while Monmouthshire (in Wales) is quite English; and the English-Scottish border counties are probably more similar to each other, than they are to the other parts of Scotland and England.
(e.g. In the Middle Ages, at the time of Robert the Bruce, my Charlton ancestors in the North Tyne valley of Northumberland were ruled by Scotland.)
But the Western Islands and Highland North of Scotland seem to be racially Irish, having apparently been settled by the Irish (displacing the Picts, and others). And of course the English colonised Ireland in various phases from the Elizabethan era; and then were mostly purged from the southern parts during the twentieth century.
I regard myself as definitely English, but I am nonetheless a quarter
Irish; and have been very aware of the bad socio-political relationships between the nations; which far too
many people (at high and low levels) delight in sustaining and exacerbating.
So much for politics. So much for the sins of resentment and spite...
But at the deepest spiritual level; there does seem to be a solid complementarity between Ireland and mainland Britain - as partly represented by the role of Irish monks and nuns in the Christianisation of the mainland in the centuries after the Roman armies left Britain in the 400s. In the other direction, St Patrick was likely born in 'England' and there was the astonishing literary genius of the Anglo-Irish (proportionately much greater than either the Anglos or the Irish separately).
Ultimately, I'm pretty sure that the ideal Albion would include Ireland.
