PROTEST is as old as the hills, which has been where many armed groups of protesters have ended up. That's particularly been the case in the global south, where imperialism acts hand in glove and with impunity, aided by its local lackeys.

But from Cuba to Angola and Vietnam to South Africa, committed and organised freedom fighters have defeated colonialism, inspiring many a movement in the northern hemisphere, who have often offered them vital support and solidarity.

The Art of Protest charts a visual journey through more than a century of protest in the West, and none was more poignant than the US’s Colorado labour wars, a series of strikes in 1903 and 1904 by gold and silver miners, mill operatives and workers in the northern and southern coal fields. They were represented by the Western Federation of Miners, and legendary labour activist Mary “Mother” Jones led a successful campaign to bring national attention to the strike.
