Although no one treatise by Marx and his coworker Friedrich Engels covers all aspects of Marxism, the Communist Manifesto suggests many of its premises, and the monumental Das Kapital develops many of them most rigorously. Many elements of the Marxist system were drawn from earlier economic and historical thought, notably that of Georg Wilhelm Friedrich Hegel, the comte de Saint-Simon, J. C. L. de Sismondi, David Ricardo, Charles Fourier, and Louis Blanc; but Marxist analysis as fully developed by Marx and Engels was unquestionably original.
