The Field
St Peter's Field was an open piece of ground near the centre of Manchester, roughly where St Peter's Square and the Midland Hotel stand today. In 1819, it was just a field. There was nothing remarkable about it. It was used for public meetings, fairs, and gatherings. On the morning of 16 August 1819, it became the site of the most significant political event in Manchester's history.
Manchester in 1819 was one of the largest and fastest-growing cities in England, but it had no Members of Parliament. The constituency boundaries, unchanged since the medieval period, meant that tiny boroughs with a handful of voters sent MPs to Westminster while Manchester, with a population of over 100,000, had no parliamentary representation at all. The city that was powering the industrial revolution had no voice in the parliament that governed it.
Across Lancashire and the north of England, working people were demanding reform. Wages were low. Food prices were high. The Corn Laws kept bread expensive. The end of the Napoleonic Wars in 1815 had brought mass unemployment as soldiers returned home and wartime industries contracted. The frustration was widespread, and it was growing.
The Meeting
The rally on 16 August was organised by the Manchester Patriotic Union Society and its allies across the region. The principal speaker was Henry Hunt, a radical orator from Wiltshire known as "Orator Hunt," who was one of the most prominent campaigners for parliamentary reform in the country. The demands were straightforward: the right to vote, parliamentary representation for Manchester and the industrial cities, and the repeal of the Corn Laws.
People walked for miles to attend. They came from Oldham, Rochdale, Stockport, Ashton-under-Lyne, Middleton, Bury, and towns across Lancashire. They came in organised groups, marching behind banners and accompanied by bands. Contemporary accounts describe them dressed in their Sunday best. Women and children were among the crowd. They were peaceful. They were orderly. They were exercising what they believed was their right to assemble and petition for change.
Estimates of the crowd vary, but most historians put the number at between 40,000 and 60,000 people. It was one of the largest political gatherings ever held in England. The field was packed. Hunt arrived on a platform near the centre of the crowd at around 1pm.
The Charge
The local magistrates had been watching the crowd gather with increasing alarm. They were stationed at a house on the edge of the field, overlooking the scene. As the crowd grew, they decided to arrest Henry Hunt and the other speakers on the platform. They issued a warrant and sent in the Manchester and Salford Yeomanry, a volunteer cavalry force made up largely of local businessmen and shopkeepers on horseback, to execute it.
The Yeomanry rode into the densely packed crowd to reach the speakers' platform. They were not professional soldiers. Witnesses alleged that many had been drinking. Their horses were untrained for crowd control. They became trapped in the press of bodies and began striking out with sabres. The crowd panicked.
The magistrates, believing the Yeomanry were under attack, then ordered the 15th Hussars, a regular cavalry regiment, to disperse the crowd. The Hussars charged. Within minutes, St Peter's Field was a scene of carnage. People were crushed, trampled, and cut down as they tried to flee. The cavalry pursued them into the surrounding streets. The entire event, from the first charge to the clearing of the field, lasted less than 20 minutes.
"They walked miles to ask for the right to vote. The cavalry cut them down. Now their names are carved in stone on the spot where they fell."
The Dead
Eighteen people were killed at Peterloo or died from injuries sustained that day. Around 650 to 700 were injured, many by sabre cuts, many more by crushing. The dead included men, women, and at least one child. They came from across the region: Manchester, Salford, Oldham, Ashton-under-Lyne, Eccles, Saddleworth.
Among the dead were John Lees, a former soldier who had fought at the Battle of Waterloo four years earlier and who reportedly said that Peterloo was worse; William Fildes, a two-year-old child knocked from his mother's arms and trampled; and Mary Heys, a mother of six from Oxford Road who was ridden over by the cavalry. She was pregnant; she gave birth prematurely and died of the consequences on 17 December 1819.
The name "Peterloo" was coined almost immediately, a bitter ironic reference to the Battle of Waterloo in 1815. The contrast was deliberate: the same government that had celebrated the defeat of Napoleon was now sending cavalry to cut down its own citizens for the crime of asking to be represented in Parliament.
The Aftermath
The government's response was not to condemn the magistrates but to congratulate them. The Prince Regent sent a message of thanks. Parliament passed the Six Acts, a series of repressive measures that restricted public meetings, imposed stamp duties on newspapers, and gave magistrates even greater powers to suppress dissent. In the short term, Peterloo was followed by crackdown, not reform.
But the massacre changed the conversation permanently. The Manchester Observer, which had championed the reform movement, was prosecuted into closure. In its place, a group of Manchester businessmen founded a new newspaper dedicated to reporting the truth without government interference. They called it The Manchester Guardian. It was first published on 5 May 1821. It is now simply The Guardian, and it remains one of the most widely read newspapers in the world. Peterloo is the reason it exists.
Parliamentary reform came slowly. The Great Reform Act of 1832 finally gave Manchester its first two MPs and began the process of dismantling the rotten boroughs. It was a start, not an end. Universal suffrage would take another century. But Peterloo had proved that the demand for representation could not be silenced by cavalry charges, and the ruling class knew it.
The Memorial
For 200 years, there was no proper memorial to the Peterloo Massacre. A small plaque on the wall of the Free Trade Hall, which was built on part of the site in the 1850s, was the only marker. The Free Trade Hall itself was eventually converted into a hotel. The plaque remained, but it was easy to miss.
In August 2019, on the 200th anniversary, the Peterloo Memorial was finally unveiled on Windmill Street, on the forecourt of Manchester Central (the former Central Station). It was designed by the artist Jeremy Deller. The memorial is a landscaped hill of eleven concentric steps carved from stone, rising to a central point. Each step is engraved with the names of the people who died, the towns they came from, and the words of the banners they carried that day.
It is a quiet, powerful piece of public art. There are no statues, no swords, no horses. Just names, places, and words carved into stone. It is exactly right for what it commemorates: ordinary people who came to ask for something they should never have had to ask for, and who paid for it with their lives.
St Peter's Square is now one of the busiest transport interchanges in Manchester. Thousands of people stand at the Metrolink stop every day, waiting for trams, checking their phones, drinking their coffee. Most of them have no idea that the ground beneath their feet is where British democracy started bleeding. Peterloo didn't happen in London. It happened here. And the fact that it took 200 years to put up a memorial tells you something about how long it takes for power to acknowledge what it did.
