Written in 1902, at a critical juncture for Russian Marxists, "What Is to Be Done?" is not merely a political tract but the foundational text of the Bolshevik movement. In it, a young Vladimir Ilyich Lenin confronts the pressing question of how to build a party capable of leading the working class to victory. Rejecting both the complacency of "economism" and the spontaneity of trade unionism, Lenin argues with fierce logic and polemical force for a new kind of revolutionary organization: a centralized "vanguard party" of dedicated, professional revolutionaries. This party's task is to inject advanced socialist consciousness into the workers' struggle, guiding it from mere economic demands to a decisive political revolution against Tsarism and capitalism. This work lays out the core Leninist principles of party discipline, ideological purity, and unwavering commitment that would shape the course of the 20th century. A crucial read for understanding the origins of communist theory, the mechanics of political organization, and the relentless will required to turn theory into world-changing practice.
