Walkers will today retrace the routes to Manchester taken by tens of thousands of campaigners before the infamous Peterloo Massacre.
Eighteen people were killed and hundreds injured when cavalry and soldiers charged a peaceful rally to lobby for parliamentary reforms on August 16, 1819.
They had walked to St Peter’s Field in Manchester – now part of St Peter’s Square – to call for national change.
The bloody massacre and the outcry it sparked shaped British democracy.
Marches will be following the original routes to Manchester from Bolton, Eccles, Middleton, Salford and Stockport.
Paul Fitzgerald, chairman of the Peterloo Memorial Campaign, said: “We hope these marches will be the first step in our aim to recreate the entire web of thousands of people who marched into the city centre on that fateful day."
The various marches will converge at 1pm at the site of the original protest, the plaza in front of the Manchester Central convention centre. The names of the dead will be read out in front of civic dignitaries.
