Das Kapital and preparatory work (especially regarding the theory of surplus value), the first volume appeared in 1867 as "The Production Process of Capital". After Marx's death in 1883, from manuscripts and the first volume Engels introduced Volume II: "The Circulation Process of Capital" in 1885; and Volume III: "The Overall Process of Capitalist Production" in 1894. These three volumes are collectively known as "Das Kapital". "Capital, Volume I" (1867) is a critical analysis of political economy, meant to reveal the contradictions of the capitalist mode of production, how it was the precursor of the socialist mode of production and of the
Capitalist mode of production (Marxist theory) title, "Das Kapital"), as a whole that provides his "definition" of the capitalist mode of production. Nevertheless, it is possible to summarise the essential defining characteristics of the capitalist mode of production as follows: In examining particular manifestations of the capitalist mode of production in particular regions and epochs, it is possible to find exceptions to these main defining criteria, but the exceptions prove the rule in the sense that over time the exceptional circumstances tend to disappear. As mentioned, Marx never explicitly summarised his definition of capitalism, beyond some suggestive comments in manuscripts which he did not publish himself.
