One report I saw speculated that a severe jousting outcome (falling off a horse in full armor can have the same effect on the body as a 45mph crash sans seatbelt) let to his personality shift.
Something happened; he went from vigorous, dashing and (relatively) sane and benevolent ruler to a deadly tyrant, supposedly in a short period of time.

“Something happened; he went from vigorous, dashing and (relatively) sane and benevolent ruler to a deadly tyrant, supposedly in a short period of time.”

During the last year or so of his marriage with Anne, Henry got into a major accident at a joust that rendered him completely unconscious for hours on end, literally comatose. He woke up, got better, and then seemed to go on a rampage, killing his wife and members of her fmaily and friends. Add in the NEED for a son to succeed him and he then went off the rails.
