I mean, Henry certainly _claimed_ that it was an annulment, but it was self-granted, on a basis seemingly made up for the occasion, so realistically considering it to be an annulment was a _bit_ of a stretch.

(Not that this was exactly unprecedented; the whole thing kind of came to a head because the Pope wouldn't grant a spurious annulment to cover a divorce to Henry, but various Popes had certainly granted dodgy annulments to various monarchs _before_.)
