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.
