Margaret Pole: Short Video History
I found a short 5-minute video on YouTube called, "Lady Margaret" - about the life of Margaret Pole, Countess of Salisbury. It's very entertaining and educational at the same time, please take a minute to check it out as it was created by Historic Royal Palaces. It touches base on the Wars of the Roses, the impact she had on Princess Mary's (later Queen Mary I) life, her son Reginald Pole's betrayal of the King and her ultimate execution.
