Why 1483 of all imaginable years?
Why would just Scotland and Ireland do it? The king of England also ruled Ireland.
And he was a different man to the king of Scotland.
I would guess it would ASB, just because Ireland and Scotland have celtic heritage it doesn't mean that they automatically love eachother and have the same exact cultures.
It was a feudal country. Its hard to define what counted as independant and what counted as part of the country. Its the same problem as with trying to make maps of France and Germany in the time period.Yes, but looking at Roberto's map, since England had control of only Dublin, I had come to the same conclusion as above.
I know this is earlier, but there is a possible POD.
You know Robert the Bruce's brother? He came to 'liberate' Ireland from the English when Edward II was King. He failed of course, the Irish were massacred; but if he succeeded, then perhaps Ireland could be Scottish, or at least in personal union with Ireland....
I doubt you'd find much pan-celticness in the 15th century though even if you do install modern nationalist thinking. Scotland by this time had well and truly became a anglo-saxon country with the celts being those scary poor people up in the hills.
