This powerful book takes a close look at the relationship between the Bolshevik party and the democratic aspirations of rank-and-file workers in Moscow in the crucial early years of the Russian revolution. Simon Pirani’s prodigious utilization of local party and secret police archives allows him to show how the Bolshevik party leadership systematically destroyed democratic voices on the shop floor: the party offered a "social contract" that promised improving standards of living in exchange for the loss of a political voice.
