battle of BosworthWatch
Henry VII's mother Margaret Beaufort was very adept at cultivating allies that would be of benefit to her son's ambitions to reign as King of England.
She married Thomas Stanley, Lord High Constable- an ancient position of commander of the royal armies.
Stanley defied Richard III's orders to send his force to join the fighting at Bosworth Field although his forces was present there and placed the crown on his stepson Henry's head after Richard was killed.
Margaret Beaufort also negotiated the marriage of her son to Yorkist princess Elizabeth of York, which brought Henry the support of many Yorkist allies.
It has also been speculated that Margaret Beaufort could well have been responsible for slandering Richard to decimate his reputation and support base.
There certainly were vicious rumours at the time being spread alleging that Richard had murdered his two young nephews the princes in the tower and was having an incestuous liaison with their teenage sister Elizabeth of York.
Both stories character assassinated Richard III during his lifetime and benefited the Lancastrian side led by Henry VII.
After Richard's death, the situation was quite different when he became engaged to and then married the maligned Elizabeth of York.
