Record revealed

The Monteagle Letter

Is this the most famous anonymous letter in British history? Perhaps it should be. Without it, the Gunpowder Plot might have succeeded – and a king and his parliament been destroyed.

Why this record matters

Date
26 October 1605
Catalogue reference
SP 14/216

On the night of 4 November 1605, Guy Fawkes was found in the vaults beneath the House of Lords with 36 barrels of gunpowder. Under questioning, he admitted that he and others planned to blow up the House during the State Opening of Parliament on 5 November. The plot would have killed not only King James I (and VI) but members of his family, his chief ministers, and the Members of Parliament in attendance. Treason of the highest order.

We don’t know who wrote it, but according to a contemporary, this note was ‘delivered to Lord Monteagle’s footman as he passed in the street, directed to his Lord by an unknown party, written in a disguised hand without date or name’. It was a tip-off – a plea for Monteagle to stay away from his seat in Parliament that day, to avoid the explosion planned.

However, Lord Monteagle did not take the warning and burn the note as it had asked. He showed it to the Privy Council – the king’s advisors – and King James agreed to try to catch the conspirators in the act. A plot that, unfortunately for Fawkes and his companions, did succeed.
