“Defiant”…Interesting editorial choice for a woman insisting that her marriage was quite valid. Henry’s actions merely showed himself a serial adulterer. Defiant might describe him, but not Katherine. She was the victim here and Sir Thomas More, friend of Henry, lost his life standing up for that same truth.

You seem to be thinking of some ideal "correct" state to defy.

Not to knock your personal beliefs, but Henry VIII was head of the country and the country was England so that made him the head of the church, too. There was nothing greater to defy than the king.

And she was defying him.
