SuccessionAct broke new ground by laying down that, in the absence of a legitimate heir, the king could determine the succession by will or by letters patent
1536
This could theoretically have led to the Duke of Richmond succession, but the latter's death ended this possibility
Henry acquired a legitimate male heir in PrinceEdward
1537
The fact that Henry had not married Edward's mother, Jane Seymour, until after the deaths of both Catherine and Anne meant that Edward's legitimacy could not be denied by any interpretation of canonlaw
Henry confirmed the succession arrangements in his will
30th December 1546
The will further laid down the right of succession to the heirs of Henry's sister, Mary Duchess of Suffolk, if Edward, Mary and Elizabeth died without issue
The will also set up a regencycouncil to act on Edward's behalf
