The Peterloo Massacre occurred on August 16, 1819, when around 60,000 working-class people gathered in Manchester to demand voting rights, leading to a violent response from local magistrates and soldiers that resulted in 11 deaths and 400 injuries. In the aftermath, the government introduced the 'Six Acts' to suppress public dissent and control the press, further curtailing the rights of working-class citizens. The event highlighted widespread social unrest and the government's fears of revolution amidst rising unemployment and high food prices.
