In the fiery crucible of World War I, the socialist dream faced its ultimate test. As national armies marched and imperialist powers clashed, the great workers' parties of Europe confronted a stark choice: uphold the internationalist pledge of working-class solidarity, or succumb to the siren call of patriotic fervor. In this incisive and furious polemic, written in the midst of the carnage, Vladimir Lenin delivers his damning verdict. The Collapse of the Second International is a forensic dissection of betrayal. Lenin argues that the decision by the majority of socialist leaders—his former comrades—to support their own national governments in the war did not represent a simple mistake, but the catastrophic and inevitable failure of an entire political tradition.
With relentless logic, he exposes what he sees as the rotten core of "opportunism" and "social-chauvinism" that had grown within the pre-war socialist movement. For Lenin, the collapse was not merely organizational; it was a profound ideological bankruptcy that cleared the ground for a new beginning.
This essential work is more than a historical document. It is the foundational manifesto for a revolutionary break, laying the intellectual groundwork for the future Third (Communist) International and defining the uncompromising principles of Bolshevism on the world stage. Here, Lenin sharpens the tools of Marxist analysis to explain why the old International died, and to declare the urgent necessity of building a new, genuinely revolutionary one in its place.
