Edward Palmer Thompson (1924-1993) can undoubtedly be considered one of those historians who founded the perspective of English social history, along with Eric Hobsbawn, Raymond Williams, Christopher Hill, Rodney Hilton and George Rudé, among others. This approach emphasizes the view through which historical processes are constructed from popular subjects, who burst in "from below" in the formation of movements and expressions of rebellion that constitute a fertile field of historiographic analysis. However, E. P. Thompson was not only an outstanding historian, he was also a militant intellectual committed to causes in favor of peace, disarmament and the anti-nuclear struggle. He was also a vehement anti-fascist fighter and this book arises precisely from his inspired poem dedicated to comrade Salvador Allende, after learning about the coup d'état and the death of the president in La Moneda Palace.
