Victorian illustration to download showing the march of the International Democratic Association to a rally in Hyde Park in support of the Paris Commune, 16 April 1871. A band plays, and the working men carry the banners of the IDA and the Commune. Boy match-sellers ply their trade. The IDA was affiliated to the International Workingmen’s Association, an international organisation of workers, which had been founded in London in 1864 – the meeting had been attended by radical thinkers from all over Europe, including Karl Marx. The Commune, a radical socialist and revolutionary government, briefly took control of Paris after the Franco-Prussian War.
