The Cato St Conspiracy 23rd February 1820 & Lords Cricket Ground
The Cato St Conspiracy took place 206 years ago.
A group of radicals led by the veteran agitator Arthur Thistlewood had determined to attack a Cabinet dinner in Grosvenor Square and thereby spark a nationwide rising. It was in part a reaction to the Peterloo Massacre in August 1819 but was also part of a much wider revolutionary current stretching back into the last years of the eighteenth century.
Cato Street is in Marylebone not that far from what is (and was then) the site of Lord’s Cricket Ground. It is one of the last places one would associate with a revolutionary conspiracy.
However two of those tried for the Cato St conspiracy at the Old Bailey in April 1820 lived near to Lord’s and a number of the witnesses called were employees at the ground.
The reference to Davidson living near Lord’s ‘in the new Road’ (Marylebone Rd)suggests that this may have been at one of the earlier locations of the ground before the move to the current site in 1814. He was said to wander the ‘rough streets’ near Lord’s Cricket Ground late at night to intimidate some of the residents. His perspective may of course have been rather different.
Conspirators
The Prisoner Davidson has been in the Cabinet maker line and resided for several years in a small tenement at the back of Lord’s Cricket Ground in the new Road and appears to have been actively engaged since the Manchester Meeting in attending both at public and private meetings.
