Mary Stuart

Mary Stuart, also known as Mary, Queen of Scots, was a Queen of Scotland.

The Doctor advised Mary, Queen of Scots to change her muckspreader. (PROSE: Tragedy Day)

She was involved in 's plan to befriend several Tudor women in an effort to prevent the reign of James I, who created the charter for St Luke's University, thereby preventing her imprisonment in the Vault. (PROSE: Girl Power!)

Iris Wildthyme claimed to have met Mary, Queen of Scots in Edinburgh while travelling with the Fourth Doctor and Sarah Jane Smith, during which she saved the Doctor's life. Mary crocheted a seat cushion for her. (PROSE: Verdigris) Iris later witnessed Mary's execution. (PROSE: The Scarlet Empress) Mary was beheaded because Elizabeth I, her cousin, suspected she was plotting against her. (PROSE: Girl Power!) According to a National Portrait Gallery poster in a Coal Hill Academy history classroom, Mary was not only a Scottish ruler, but a Catholic martyr and a talented golfer. (TV: The Coach with the Dragon Tattoo)

In the far future, the creators of EarthWorld confused her with Marie Antoinette, proclaiming the latter to be Queen of Scotland. An android replica of Mary was built and executed, despite its pleas for mercy. The Eighth Doctor corrected them and told them that Mary died with dignity and it took more than one blow to sever her head. (PROSE: EarthWorld)

Behind the scenes

 * In The Witchfinders, much information about James I's mother is given although she is not established in-universe as Mary. Though Girl Power! counts Mary as one of the Tudor women befriended by Missy, and makes the suggestion that Missy intended to prevent James I from being conceived, it falls just short of explicitly identifying Mary as James' mother.
 * She was played by Vanessa Redgrave in the film Mary, Queen of Scots and Barbara Flynn in the miniseries Elizabeth I.
