How the Gunpowder Treason was discovered
Reading time: 9 minutes
On the night of 4 November 1605, a man calling himself John Johnson was found in the vaults beneath the House of Lords with 36 barrels of gunpowder. Under questioning, Johnson – whose real name was Guy Fawkes – admitted that he and his co-conspirators planned to use the gunpowder to blow up the House during the State Opening of Parliament on 5 November. If successful, this plot – which became known as the Gunpowder Treason, or Gunpowder 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 at the state opening. This was treason on an unprecedented scale – an attempt to destroy both the king and his government.
