To be honest Anyanka, England really din’t hold much of attraction for Charles. The whole reason Arthur/Henry and COA’s marriage took place was more to do with that at the time H7 neded to prove that he was a self made king and was here to stay sort of thing. Plus England was pretty skint after all the years between the wars between the roses. Spain being one of the richest countries of the known world at the timeit seemed a good idea to H7 at the time to 1. prove that the Tudor Dynasty was here to stay and 2 rebuild a very threadbare treasury.

Spain had gained very little from the match and Mary was just a girl Granted Charles was engaged to her but again England still had nothing to appeal to Charles. Charles was a warrior and was always poking his beak into other countries problems some of which he probably started. H7 and H8 had brought peace to England so there was little point for him to be bothered in his aunt’s affairs he wouldn’t gain anything from it. If he had supported his aunt during her divorce and lets say for the sake of arguement turfed H8 off the throne in favour of his aunt and in time Mary England would have been ruled by 2 woman COA was a capable woman and there’s no doubt she would have been a very good monarch but up until H8 changed the law woman had never ruled as Queen in their own right as we know. So in my opinion all that would do is create more problems as England would be a mass battleground for those left after H8 had finished chopping up all those he saw as a threat to the throne to claim the throne, and if mary had lived through these political squabbles she would be used as a pawn by those who wanted to seek power for themselves.
Does that make sence?…
Much the same opinion I think with the Danish lot.
