Here is my take on Henry VIII's wives:
Catherine of Aragon:
Promised to her when he was a child. Married her, under immense pressure, and sired one daughter - Princess Mary. Divorced Catherine and broke with the Church of Rome to marry,
Anne Boleyn, mother of the Great Gloriana, aka Queen Elizabeth I, one of Britain's most intellectually accomplished monarchs, if not the most, since the Plantangenant, Henry II. Trumped up charges against Anne, Elizabeth's mother (his only official 'murder') enabled Henry to marry,
Jane Seymour, whom all evidence supports, he genuinely loved, at least as much as he'd loved Anne Boleyn. The mother of his only son, Jane died of puerperal fever (a common ailment), and to assuage his genuine grief at her death, and to consolidate Protestant alliances, Henry was persuaded to then marry,
Anne of Cleves, a clever and discerning woman who was, intellectually, Henry's match, and a woman who skilfully managed the marriage's annulment, upon which he married,
The very young and pretty Catherine Howard, a scion of a prominent family who had great ambitions to see a Howard on the throne. Some might remember that the Howards tried, so very hard, to deny Elizabeth her throne. Catherine, was manipulated by her ambitious family and finally brought to ruin by her sexual adventures. Caught, in flagrante delicto, there was absolutely nothing that King Henry could do to save her. What Catherine did was, according to the law of the land in its day, High Treason. Reports exist which assert that Henry wept for Catherine because he could do nothing to save her.
Katherine Parr, Henry's last wife, outlived him. In my view, least said about her, the better..
Henry VIII may well have been a King who brought trauma and relgious and social dislocation to his country. I can't argue with that.
However, in my opinion, he most cruelly and jealously killed but one wife (and one, of course, is quite enough), but not six.
Despite everything, Henry VIII was a man of immense intelligence, with a highly developed, educated and well-formed mind, which only one of his children, obviously, and according to historical record, inherited.
It's such a pity that he didn't live in C21 when he would have been so gratified to know of the immense admiration which his most accommplished a clever child, Elizabeth I, still enjoys, after 500 years.
