First published in 1867, Capital, or Das Kapital, is the infamous treatise on economics and capitalism by Prussian revolutionary KARL MARX (1818-1883), who changed history with his 1848 book The Communist Manifesto.

In this work, edited by Marx's friend, German philosopher FRIEDRICH ENGELS (1820-1895), Marx systematically analyzes the way the capitalist machine functions. In this academic work written for students and serious thinkers, he explores wages, competition, banking, rent, and the natural laws that seem to govern the development of capitalism without any oversight by the society in which it developed.

Originally published in three volumes, Capital is here presented in five volumes. Volume III, Part 1 covers:

. The Conversion of Surplus-Value into Profit and of the Rate of Surplus-Value into the Rate of Profit
. Conversion of Profit into Average Profit
. The Law of the Falling Tendency of the Rate of Profit
. Transformation of Commodity-Capital and Money-Capital Into Commercial Capital and Financial Capital
. Division of Profit Into Interest and Profits of Enterprise
