whose history?

The situation of Mary Stuart is that Elizabeth I, the Protestant daughter of Henry VIII (see this post for reference), is Queen of England and Mary, formerly Queen of the Scots, a devout Catholic, is in prison in London for murdering her husband and plotting against the English throne.  Egged on by various plotters and courtly connivers, the two engage in contest of wills:  Mary seeks to be freed, while Elizabeth hesitates to execute her for ethical reasons and to avoid turning her into a martyr for the Catholic cause.  Mary is finally executed, Elizabeth claiming it was done without her specific bidding.
