Working class people held large meetings to protest against the political system. One such meeting happened in Manchester at St Peter’s Fields in August 1819.
Around 50,000 people arrived at St Peter’s Fields from all around Manchester.
Henry Hunt (a radical speaker) was due to make a speech calling for the reform of Parliament.
Manchester at this time had no police force, so the army were sent to prevent any disturbances. When Hunt began to speak the army attempted to arrest him, and attacked anybody who got in their way.
Eleven people were killed and 400 were injured.
