Wednesday 11 September marks the 51st anniversary of the 1973 coup that overthrew president Salvador Allende in Chile and installed the brutal Pinochet dictatorship. We republish here a document written in 1979 by Alan Woods, analysing the history of the Chilean labour movement and the period of the Popular Unity coalition government of Allende. Who was behind Pinochet's coup? What interests was he defending? What were the policies of the Allende government and why despite all warnings was he unable to prevent the coup?

In this latest video from our series on the 1917 Russian Revolution, Alan Woods - author of "Bolshevism: from Revolution to Counter-Revolution" - discusses the failed coup attempt by General Kornilov and the impact this had on the political consciousness of the masses.
