Lenin's Struggle for a Revolutionary International is the first in a series that will publish the documents of the Communist International in Lenin's time. It covers the years 1907-16, charting the Socialist International's efforts to counter the threat of world war, its collapse when war was declared in 1914, and the subsequent effort led by the Russian Bolsheviks to reestablish working-class unity and build a new revolutionary International. Featured in this book are procedings from international socialist conferences; debates amongst socialist leaders such as Karl Kautsky, V.I. Lenin, Rosa Luxemburg and Leon Trotsky; and all the statements of the Zimmerwald Left, forerunner of the Communist International.
