​The Cato Street Conspiracy of early 1820 was a terrorist plot to murder all the British cabinet ministers and Prime Minister.  Led by Arthur Thistlewood, the conspirators were known for being a revolutionary organization, involved in unrest and propaganda and plotting the overthrow of the government.  But the police had an informer and the plotters fell into a police trap and 13 were arrested, while one policeman was killed. Five conspirators were executed, and five others were transported to Australia.  This once notorious plot has become less well known in recent years and yet the documentary evidence and associated images are fascinating.  Drawing on contemporary accounts and pictures in Guildhall Library’s collections this exhibition tells the story of the conspiracy, its participants and their ultimate fate.
