Mi idea for segregating Wales was precisely the rise of Arthur II as king. It is something purely speculative to give some flavour to the TL. The English kingdom starts to decompose due to debilitation of royal authority and loses of lands.
Okay, I could see this as causing a lot of problems for the monarchy...then again, those who lose their lands also have lost their livelihood to a degree, making for a poor resistance. Of course, as they begin to see the handwriting on the wall (seawall, that is), that could change.
Henry VII attempts to seize Scottish lands, but the kingdom of James IV is in better shape and he is defeated.
No, it isn't, actually. By the time this would happen, England wouldn't be that weakened, and the fact is that at a similar point in history, Henry VII defeated James IV in battle very badly, at Flodden.
If the English decide to take that land, they will probably succeed. The Scottish are unlikely to get much aid from France, given the fact that the French have their own issues to deal with due to the rising waters.
Several Yorkist conspiracies appear.
Henry VII probably won't die, unless you want him to, for your timeline as you say. A lucky arrow strike in battle with James IV might have taken out Henry VII and turned the tide of battle, as you had previously, I suppose.
There is a movement in Wales to stop the english refugees looking for higher lands and the regent uses the title of Arthur as prince of Wales to look from some support. Finally the authority is only recognized in Wales.
Such a movement is doomed to failure. The English will get in just by shear numbers. As for Arthur being used to keep the English out of Wales, it just doesn't ring true to me somehow. Arthur's Regent would be wanting to keep power over the Welsh and English, not have a separatist movement, I'd think. Who were you thinking for this role anyway, and when would all of this be occuring?
Remember, your flooding is happening over the course of a century. This isn't going to all happen in 1493...also remember that initially, most people will not believe that this can keep going on for as long as it will.
No, I think initially you would see history playing out much as it did OTL, except with some twists, and some butterflies such as Arthur living (then again, he wasn't considered the most hale of individuals, so maybe he dies of some plague regardless).
Henry VII and James IV are both excellent leaders. They will do the best by their countries, and initially I don't think that we will see them clashing head to head. The question will be, will there be a holy alliance against France ITTL, and if so, will England join it? That has serious ramifications...
About the migration of the british (english, irish, and to less extent welsh and scottish), would it be feasible to move such an amount of population to the other side of the Atlantic.
Over a century, yes.
My original idea was to have most of the english and irish moving in Europe: France, Spain, Scandinavia and from there to eastern Europe,
The problem is that the British Isles refugees will have to either find a patron or fight their way ashore, and then keep fighting to move inland. Quite frankly, those who go to the New World will have an easier time because they will meet less opposition as they migrate inland. So while a substantial number will move to the Continent, as time goes by more and more will go for the land in the New World, which just needs to be taken from a relatively smaller amount of poorly equipped Native Americans, as opposed to the more populous and heavily armed Europe.
but some of them would move to North America. We could have an Irish nation in Quebec (with a warmer climate than in OTL) and English in New England. The Scottish would favour France due to the Auld Alliance.
I don't think you'd see an independent Irish nation in America, rather an 'English' nation comprised of Irish, English, Welsh, and Cornish, and a 'Scottish' nation composed of Lowland and Highland Scots.
I was also thinking in having an Spanish expansion in North Africa. Some sort of continued Reconquista that would attract lots of colonist-refugees.
Why would this happen?
One more question: we would have tornados and hurricanes in the North African Coast and in the Iberian Peninsula instead than inthe Caribbean, wouldn't we?
No, you'd still have them going across to the Caribbean. They'd be stronger, but move slower, I think.
