That is your opinion - not mine.
After her son's denounciation and her faith she could easily have been the focus for an uprising that could have seen hundreds or even thousands die - Henry acted because he needed to do so.
Seems we are bound to be diametrically opposed to one another in our views..
Why would any potential uprising focus on a
67 year old woman? Certainly, she was the last of the Plantagenets, but even so, at that age and in view of her gender, do you really believe any uprising would place her on the throne of England? Or even make her a cause worth dying for?
The average life expectancy of a woman during that time was about 30-40 years. Margaret Pole was positively ancient at the age of 67.. and England would not have it's first queen regnant until after Edward VI's death.
Margaret herself would have probably opposed any uprising on her behalf.. though she was a firm Catholic, she was also a loyal subject of her king. She was godmother to and practically raised Princess/Lady Mary, and was in charge of her household until Anne became queen. She was even at court after Anne Boleyn's fall from grace.. until Reginald Pole sent his treatise to Henry's court.
By the time of Margaret Pole's execution, two of her sons were already dead.. and of the two that were still living in exile, Reginald was a priest without issue. The other, Geoffrey, had left his family in England while he escaped to the continent.
If, as you say, Henry VIII acted because he needed to do so.. then why were the sons of Lord Montagu and Sir Geoffrey allowed to live?
Surely they could have also been the focus of an uprising.. since any one of them technically they had a better claim to the throne than Henry or his children. Henry Pole, 1st Baron Montagu (executed), left two sons;
Thomas and
Henry - Sir Geoffrey Pole left five;
Arthur,
Thomas,
Edmund,
Geoffrey and
Henry - Yet there were no uprisings to put them there.. before or after Henry VIII's death. Nor after Edward VI's death either.
And why was Sir Geoffrey allowed to live? He was imprisoned for two months in the tower, but was apparently released.. if anyone could have been the real focus of an uprising, it would have been Geoffrey, who was male.. who had sons to succeed him.. and who would have been much preferred above his old and frail mother.
Henry VIII was enraged by Reginald Pole and his published treatise - and murdering Margaret Pole was his public retaliation for Reginald's public denounciation of his policies.
