The Wars of the Roses ended in August 1485 when Henry Tudor defeated Richard III at the battle of Bosworth. However, Henry would never have become king and founded the Tudor dynasty without his mother, Margaret Beaufort. Historian Dan Jones concludes his history of the feud by revealing how the widow kept her only son safe as England descended into chaos and why she embarked upon a bold but risky plan to place him on the throne. Last in the series.
