Considering neither of the first two King Chucks are particularly well remembered (one was beheaded, the other was deposed but later re-hired), it never bode well that he chose to be crowned using his birth name.
He’ll probably be best remembered as “King Charles the Divorced,” since he’s the only king who was divorced (much less divorced and remarried) when crowned that the UK, Great Britain, or England ever has had.
Henry VIII divorced two of his six wives.
