Lady Margaret Beaufort was a prominent figure in 15th-century England, known for her role in the Wars of the Roses. Born in 1443, she was the mother of Henry VII, the first monarch of the Tudor dynasty. Margaret was a skilled political strategist and played a crucial role in her son's rise to the throne. As a member of the Beaufort family, she was a descendant of John of Gaunt, which gave her significant influence. After her husband's death, she became a key supporter of the Lancastrian cause, working tirelessly to secure her son's claim and ultimately helping to end the conflict between the Lancasters and Yorks.
