On this day, 8 August 1927, the radical Industrial Workers of the World union attempted a national general strike against the proposed executions of wrongly convicted Italian anarchist workers Nicola Sacco and Bartolomeo Vanzetti. It was particularly well observed in Colorado coalmines, where the stoppage was almost complete and lasted for two days. Realising their strength in the area, the IWW then stepped up its organising efforts and called more strikes in the coming months. In our podcast episode 9, we talk about the history of the IWW over this time period: https://workingclasshistory.com/2018/07/23/the-industrial-workers-of-the-world-1918-1950s/
