Mrs Eyre

She really didn't; there is no evidence to support this narrative and plenty to suggest that Elizabeth and Margaret B worked well together, even combining forces to make the king postpone young Margaret's journey to Scotland on the grounds that she was too young if the Scottish king decided not to wait to consummate the marriage. The king acknowledges in his letter to James that he is acting at the request of the Queen and his mother in this. They were involved in joint charitable works and MB kept rooms at Collyweston for the Queen permanently at the ready. The nasty old cow also put Elizabeth's sister up when she angered the king by marrying without his permission.

No, she wasn't. Her efforts while he was in exile were all focused on getting his title and patrimony back, no thought of the throne because there were about 8 people between him and it for most of his life. Edward IV and Margaret discussed Henry marrying one of Edward’s daughters, including Elizabeth of York. Edward and many others were tired of the civil strife and finally recognized the benefit of bringing Henry Tudor into the Yorkist camp. There exists a draft pardon of Henry along with the terms of his return but it was never ratified due to the unexpected death of Edward IV in April of 1483. I'm not sure where you get the idea that Henry "just signed off on" any and all demands she made. She enjoyed a position of influence and power, but the king was very much the king. Foreign emissaries remarked that although the king listened to his mother he did what he wanted. The fact is that Gregory hates the Tudors with the power of a thousand suns and there is no calumny too great (pre marital rape anyone? Beaufort murdering Jasper Tudor and the princes in the Tower? HVII being a pitiful cry baby?) for her to dream up. Take anything she writes about anyone with a shovel of salt.
