The Accumulation of Capital

The Accumulation of Capital: A Contribution to an Economic Explanation of Imperialism (German: Die Akkumulation des Kapitals. Ein Beitrag zur ökonomischen Erklärung des Imperialismus) is a 1913 book by the Marxist theorist Rosa Luxemburg. In it, Luxemburg critiques Karl Marx's theory of capitalist reproduction, arguing that capitalism requires access to non-capitalist markets and societies to solve the problem of realizing surplus value and to facilitate its expansion. She posited that this necessity for external markets drives capitalist imperialism, as advanced capitalist states are forced to violently conquer and absorb pre-capitalist areas of the world.

Luxemburg controversially concluded that once this process is complete and the entire globe operates under the capitalist mode of production, the system's internal contradictions will make further accumulation impossible, leading to its collapse. The work was written as an intervention in the contemporary Marxist debates on revisionism and imperialism and was intended to provide an economic foundation for the inevitability of capitalist crisis.

Upon its publication, The Accumulation of Capital generated fierce criticism from across the socialist movement, including from prominent Marxists such as Nikolai Bukharin and Otto Bauer. Critics accused Luxemburg of misinterpreting Marx's method, promoting a theory of underconsumptionism, and failing to understand that accumulation could be sustained internally. However, she was also hailed by others, such as Franz Mehring and Julian Marchlewski, as the most knowledgeable interpreter of Marx since Friedrich Engels. Despite the controversies, the book is considered a foundational text in Marxist theories of imperialism and has influenced later thinkers such as Michał Kalecki, Henryk Grossman, and, in the 21st century, David Harvey.
