I know who H8 was I live in his kingdom. What you say is partially correct but not totally accurate. H8 did want a divorce, in fact he wanted 4. The first Catherine of Arogon mother of Mary I, was granted by the Pope on the grounds of lack of a male heir, which was always the fault of the woman never the King. The King then needed a new dalliance to produce an heir, que his mistress Anne Bolyen the mother of Elizabeth I, no male heirs, another appeal to the Pope which was denied, This is where things start to get tense with Rome. Anne Boleyn was accused of infadelity and executed for treason.
Que Jane Seymore another Mistress but the mother of King Edward VI, Henry had a roving eye and a need for allies in Europe as the Reformation was begining, and the dispute with Rome had escallated to a political matter of soveriegnty, exit Jane conveiniently via typhus, enter Anne of Cleeves a German, the marriage was not consumated so it was annulled, and enter Catherine Howard. By this time the H8 had become corpulant and syphalitic and tyranical.
Catherine Howard was unable to have children, and in H8 was past paranoia so He asked for a third divorce again denied. This was when the Church of England was formed and all Church land was stollen and the Abbies were shut. The Crown got everything, and H8 divorced Catherine Howard via the axe. Enter Catherine Parr, who outlived H8.
H8 was succeeded by the CATHOLIC Mary I, Queen of Scots, she was deeply hated by the aristocracy and most parliments. The Lord Chamberlain (Prime Minister) plotted to have her removed by the accepted form (overthrow and axe) but she died before Parliment could move. Elizabeth I was released from the Tower and made Queen on the basis that she would uphold the Church of England and bannish all Catholics from Government, the army and positions of power. The Dissolution was complete but lasted well into the 1700s and the discrimintion continues today under the Act of Settlement 1703, and the Act of Succession 1754 where Catholics are forbidden by law to hold any government post or marry into the Royal line of succession.
It was the brutality of Elizabeth I and James I that led to the Gunpowder Plot in 1605 by Guy Fawkes, who was captured, then hung drawn and quartered, the event which is still celbrated today every 5 November
The title of Defender of the Faith was bestoded 1521 by Pope Leo X for the kings dissertation on the Seven Sacrements and their importance to the Christian Faith. H8 was a learned and devout Catholic, he had traveled to Rome and studied theology. Make no mistake despite what the Anglicans claim it is a Catholic Title only bestowed by a Pope.
Hope that clears that up for you. This is a potted version only
He was given the title before he went off the deep end. The man was excommunicated.
