Why Was Mary Queen of Scots a Legitimate Threat to Elizabeth? - Summary 

Mary Queen of Scots was a constant problem during the early reign of Elizabeth I. This stemmed from the fact that she had a legitimate claim to the throne of England. Legitimacy was vital in Elizabethan England. The people believed God chose the monarch and bestowed them with Divine Rights. To have the approval of God, an heir's bloodline had to be ‘pure’ and fully connected to a previous monarch. If doubt about a monarch’s legitimacy existed amongst the population, they could face rebellion.

Mary Queen of Scots was a member of the Tudor royal family. Unlike Elizabeth, her parents had not divorced before or after Mary’s birth. This increased Mary Queen of Scots’ legitimacy. From the perspective of an English Catholic, Mary Queen of Scots deserved to be Queen of England. She was a devout Catholic. Mary, through marriage and birth, had claims to the Scottish and French thrones. English Catholics believed that Mary, Queen of Scots could restore England’s reputation as a European power.

  • Francis Walsingham, Elizabeth’s spymaster, monitored Mary closely after the Throckmorton Plot

    • Walsingham wanted to catch Mary in the act of plotting

      • This would give Elizabeth the evidence needed to punish Mary

    • Walsingham placed spies within Mary’s household. They persuaded Mary it was safe to communicate in secret letters. Mary placed the letters in beer barrels

  • Walsingham allowed Babington’s plot to develop

    • He wanted enough evidence to incriminate Mary in treason

    • He was waiting for Mary to send a letter that showed her full involvement in Babington’s plan

    • He needed to know the names of every Catholic accomplice in the plot

  • On 17th July 1586, Walsingham uncovered the evidence needed to prove Mary’s guilt

    • Mary wrote a letter to Babington. This letter is known as the ‘Gallows Letter

      • Historians call this the ‘Gallows Letter’ because it ‘proved’ Mary’s guilt in treason and would result in her execution

    • Mary wrote to Babington that:

“Then shall it be time to set the six gentlemen to work”

  • The ‘six gentlemen’ were the men Babington chose to assassinate Elizabeth

Elizabeth enforced even harsher punishments on English Catholics. She arrested 300 recusants in London. She executed 31 Catholic priests

In September 1586, Elizabeth moved Mary, Queen of Scots to Fotheringhay Castle, Northamptonshire. Fortheringhay was closer to Elizabeth in London. The Privy Council heard Mary’s trial for treason. The government declared her guilty

Worked Example

How convincing is Interpretation A about how much of a threat Mary Queen of Scots was to Elizabeth I’s reign?

[8 Marks] 

Interpretation A: Hugh Oakeley Arnold-Forster, History of England: From landing of Julius Caesar to the Present Day, written in 1898

“While Mary was in England, plot after plot was made against Elizabeth by Mary's friends, and by men who looked to her as their rightful queen. Whether Mary knew of these plots is uncertain... Letters were found... but there were many who said then, and many who still believe, that these letters were forgeries - that is to say, that they were written by Mary's enemies for the purpose of making people believe she was guilty.” 

Partial answer:

Interpretation A is convincing as it outlines how Mary Queen of Scots' presence in England was a threat to Elizabeth. The interpretation states “plot after plot was made against Elizabeth by Mary’s friends”. Mary Queen of Scots was named in several domestic and international, plots such as the Ridolfi and Throckmorton plots. Her associations showed that Mary’s presence in England was a significant threat to Elizabeth because she was included in these plots against Elizabeth’s reign.
