The Unknown Revolution

The Unknown Revolution is a 1947 history of the Russian Revolution by Voline.

Publication
Voline finished the book in 1940 while in Marseilles. After his death in 1945, it was first published posthumously in 1947. Following 1968 events in France, the book was republished in French paperback without additional editorial content by Pierre Belfond as part of a series by Daniel Guérin and Jean-Jacques Lebel.

The book was translated into English in two parts by the Libertarian Book Club. The first volume, Nineteen-Seventeen: The Russian Revolution Betrayed, in 1954, and the second volume, The Unknown Revolution: Kronstadt 1921, Ukraine 1918–21, in 1956.

Reception and legacy
Historian of anarchism Paul Avrich wrote that Voline's book was "the most important anarchist history of the Russian Revolution in any language".
