Discover the history of the most serious crime that you can commit
‘Treason: People, Power & Plot’ was a major exhibition from The National Archives on the history of treason since 1352 and is now closed. Open Tuesday-Sunday from 5 November 2022 until 6 April 2023, the exhibition brought iconic and unknown archival documents to life, including the original Treason Act and the Monteagle Letter that tipped off the Gunpowder Plot.
From the most famous treason trials such as Guy Fawkes, Anne Boleyn and Charles I, to the cook who poisoned the porridge and the young girl tried as a witch, the exhibition showcased nearly 700 years of treasonous history. Read the accompanying book for the full history of Treason.
