"Left-Wing" Communism: An Infantile Disorder by Vladimir Lenin is a critique of certain ultra-left tendencies within the international communist movement during the early 20th century. Lenin addresses "left-wing" factions that reject participation in parliamentary politics, trade unions, and alliances with non-communist forces, arguing that these positions are immature and counterproductive.

Lenin emphasizes the importance of tactical flexibility and the need for communists to engage with existing political and social structures to win over the working class. He critiques the ultra-left for dismissing these as "compromises," asserting that successful revolution requires understanding the material conditions and using every available opportunity to advance the proletarian cause.

Through historical examples, including the success of the Bolsheviks in Russia, Lenin demonstrates how engagement with diverse groups and strategic compromises were essential in building the revolutionary movement. He warns that dogmatic approaches can isolate communists from the masses and weaken the revolutionary struggle.

The work is both a defense of Marxist pragmatism and a guide to revolutionary strategy, emphasizing the need for discipline, adaptability, and connection with the broader working-class movement. It remains a key text for understanding Leninist approaches to revolutionary politics.

The Civil War in France by Karl Marx is a detailed analysis of the Paris Commune of 1871, which Marx identifies as the first example of the working class taking political power. Written as an address to the International Workingmen's Association, Marx celebrates the Commune as a revolutionary government that sought to dismantle the capitalist state and replace it with a system of direct proletarian rule.

Marx critiques the French bourgeoisie and their collaboration with the Prussian state to suppress the Commune, framing the conflict as a class struggle between the exploitative bourgeoisie and the emancipatory proletariat. He praises the Commune's measures, such as abolishing standing armies, separating church and state, and ensuring workers' control over production. Marx also highlights the Commune's democratic structure, which sought to eliminate hierarchical governance by making officials accountable and recallable.

Though the Commune was brutally suppressed, Marx views it as a critical lesson for future revolutions, emphasizing the necessity of dismantling the bourgeois state apparatus and replacing it with a new form of governance rooted in proletarian self-organization. The text remains a foundational work in Marxist theory, illustrating the potential and challenges of workers' revolutions.

The Proletarian Revolution and the Renegade Kautsky by Vladimir Lenin is a scathing critique of Karl Kautsky, a prominent Marxist theorist who opposed the Bolshevik Revolution. Lenin accuses Kautsky of betraying Marxism by siding with bourgeois democracy over the revolutionary dictatorship of the proletariat.

Lenin defends the Bolshevik seizure of power in 1917 as a necessary step toward establishing socialism. He critiques Kautsky for misrepresenting Marx's views on the state, particularly the idea that the working class must dismantle the bourgeois state apparatus and replace it with a dictatorship of the proletariat. Lenin argues that Kautsky's preference for parliamentary democracy ignores the class realities of capitalist society, where true democracy for workers is impossible under the domination of the bourgeoisie.

The work emphasizes the importance of revolutionary action, the role of the soviets (workers' councils) as organs of proletarian democracy, and the necessity of suppressing counter-revolutionary forces. Lenin portrays Kautsky as a defender of reformism and compromise, contrasting this with the Bolshevik commitment to the revolutionary transformation of society. The text is both a defense of the October Revolution and a broader critique of opportunism within the socialist movement.
