What if events in England had been different (This replaces my old timeline which was, admittedly, badly planned and badly thought out.)
And so… to begin.
1533
April 5th: Catherine Parr's husband, Sir Edward Burgh, recovers - after a diligent bedside vigil by Catherine - from his illness and the happy couple is reunited.
September 7th: Anne Boleyn goes into labour and gives birth; a boy - Henry, who has Anne'a dark eyes and dark hair - much to the King's delight. At Ludlow Castle, Lady Mary and the Imperial Ambassador are planning an escape and, when the news of a living child born to the Queen arrives with a messenger later that day, the two flee. The Imperial Ambassador, Eustace Chapuys, returns to Spain… while Mary flees to France and the protection of King Francis.
September 8th: Thomas Boleyn, father of Queen Anne, is made Duke of Wiltshire and Ormond, while his son, George, is made Marquess of Rochford. George's title will become the subsidiary title of the Dukes of Wiltshire and Ormond. George's other reward is an annulment from the marriage to his barren wife, Jane Parker.
September 9th: When the news of Mary's flee to France arrives at Court, Henry VIII is furious… so furious in fact, that the only remaining documents on it - unearthed in a vault in 1922 - reveal that there were "several bloody and demeaning beheadings" and that a "new act of succession was immediately drawn up."
September 12th: Mary, adding a few embellishments to her escape story, arrives in France. King Francis seizes on his chance; most of the Catholic nations see Mary as heiress of all in England and so, he marries her, sick and weak, to his son, the Dauphin. The marriage is consummated - several times - immediately. Once Mary is healed, she settles herself into the French Court and begins to adjust being the Dauphine of France.
For Mary, this is a match that can help her regain her place, even if she doesn't really like the French. For the Emperor, this is a good thing, for it puts the bloodline of Spain into France and gives him another ally there.
December 3rd: Ivan IV succeeds his father Vasili III as Grand Prince of Muscovy at the age of 3.
December 13th: Eric, Crown Prince of Sweden, is born to King Gustav and Queen Catherine of Saxe-Lauenburg.
1534
January 15th: The Parliament of England passes the Act Respecting The Oath to the Succession recognising the marriage of Henry VIII and Anne Boleyn, and their children as the legitimate heirs to the throne. To Henry and Anne, Mary is now most definitely a bastard and anyone saying differently is wrong.
January 16th: Henry VIII, now 42, is insistent on still living his life like he did in his 20s and takes part in a joust to celebrate the birth of Prince Henry. He is knocked from his horse and crushed, slipping into unconsciousness for six hours. His condition is bad enough to warrant Prince Henry being prepared for a coronation. Henry VIII recovers, but his health is badly damaged and his temper ever more capricious. [1]
April 7th: Thomas More is sent to the tower for protesting to the Submission of the Clergy Act. It's only his friendship with the King and the fact that he was one of the King's childhood tutors that keeps him alive... for now.
July 12th: Mary Boleyn is exiled from court after making a love marriage to William Stafford.
1st September: Catherine Parr, wife of Sir Edward Burgh, gives birth to a son; the child inherits Catherine's constitution.
25th September: Pope Clement III dies - when "accidentally" fed some poisoned mushrooms - and is succeeded by Paul III, whose stance on the problem of Henry is, merely, "ignore it".
As Christmas arrives it is evidently obvious that Anne is pregnant again, having conceived in November.
[1] I butterflied this away from 1536 to 1534 as instead of Elizabeth being born, a son was. In celebration, Henry is harmed in the joust instead.
The title is in Latin and means "A Different England".
