The execution of Mary, Queen of Scots took place on 8 February 1587 at Fotheringhay Castle, Northamptonshire, England. After nineteen years in English captivity following her forced abdication from the throne of Scotland, Mary was found guilty of plotting the assassination of her cousin, Elizabeth I in what became known as the Babington Plot. The execution of Mary was the first legal execution of an anointed European monarch.[1]
