On this day, 31 July 1922, workers in Italy declared an indefinite general strike against fascism. However the nationalist unions did not join it, and the middle class and capitalists supported the fascists breaking the strike. After two days, the superior military organisation of the fascists broke the strike across most of Italy, with workers in Bari and Parma holding out until 7 August.
