If Henry Tudor had been cut, stunned, but roused quickly and healed within weeks, would much have changed?
I've seen speculation recently that he practically became a psychopath after the serious scrap he had in real life. Ideas on divergence?
Well which jousting injury? The one in 1524 where he suffered brain damage or the one in 1536 that crippled his leg?
Because there's nothing he did after the second accident that he hadn't already done before.
At this point he'd already had his fathers loyal servants executed in a show trial for treason they didn't commit in order to present a clean break from his father's tax laws.
Yes, the fact 1536 was a bad year for him had a huge effect on his personality. But even without the injury being crippling, his illegimate son would still have died, his first wife would still have died, he would still have faced a rebellion in yorkshire, he'd still have ill health from his head injury, etc, it wouldn't be all sunshine and light.
The one huge impact is that Anne Boleyn miscarraged just five days after his jousting accident and some blame her reaction to the news for that. Obviously that's debateable but if she doesn't miscarriage then everything changes hugely. If it's a son then yeah he has far less reason to get rid of her so in that way he'd far less of a tyrant.
And obviously being in chronic pain makes your cranky. Whether he'd still do stuff like execute loyal servants like cromwell, run show trials for wifes he wanted rid of, have parties at the death of his other wives, execute rebels after promising them amnesty and the like, I dunno. My guess is if he felt he needed to, he'd still do it (because again he did it to his father's advisors and wolsey's loyalty hadn't saved him at this point) but without his health problems he might be less prone to black moods, I guess.
If Anne Boleyn still miscarriages though, I can't see that particular tale going any different. He'd still need a son to ensure his dynasty (and still be haunted by the wars of the roses as to what happens when a king has no male heir), so he'd still be suspicious by the miscarriages and I think he's still go ahead with the show trial with the faked evidence and the execution to remove her so he can get another wife who might give him a son. I think that was pragmatic on his part rather than pain driven rage.
