Throckmorton Plot

The 1583 Throckmorton Plot was one of a series of attempts by English Roman Catholics to depose Elizabeth I of England and replace her with Mary, Queen of Scots, then held under house arrest in England. The alleged objective was to facilitate a Spanish invasion of England, assassinate Elizabeth, and put Mary on the English throne.^[1]

The plot is named after the key conspirator, Sir Francis Throckmorton, cousin of Bess Throckmorton, lady in waiting to Queen Elizabeth. Throckmorton was arrested in November 1583 and executed on 10 July 1584.^[2]
