More than 300 people gathered in Roux, Charleroi, on Friday morning to commemorate the deadly events of spring 1886, when 19 workers were killed during strikes and riots.
The unrest, which took place on 26 and 27 March, was met with heavy repression by police and the army.
In recent years, the events have been marked annually through ceremonies organised by a collective alongside the FGTB and CSC trade unions. The aim is to ensure this chapter of Belgium's labour history is passed on to future generations.
Speeches were delivered by several union leaders, including FGTB president Bert Engelaar and Fabrice Eeklaer, federal secretary of CSC Charleroi Sambre & Meuse.
Following the speeches, participants marched through the streets of Roux to honour those who lost their lives and their legacy.
