As a prisoner in England, Mary found herself the focal point of several Catholic plots to free her.
Most of the plots involved murdering the Protestant Queen Elizabeth and placing Mary, the Catholic Queen of Scotland, on the throne of England. Wisely, Mary did not become involved in these plots.
As the years passed, Mary realised that she might never be released. In 1586 she replied to a secret letter from Anthony Babington. As with earlier plots, Babington and his fellow conspirators planned to kill Elizabeth and make Mary Queen of England.
Unfortunately for Mary, she had been trapped. English secret agents had always known about the plot and Mary was charged with treason.
Elizabeth, however, couldn't bring herself to execute her cousin. Months passed before Elizabeth's advisors pressured her to sign the death warrant.
On the 8th Feb 1587 Mary was beheaded at Fotheringhay Castle in England.
