It can be said of very few books that the world was changed as a result of its publication - but this is certainly the case of Capital: A Critique of Political Economy by Karl Marx (1818-1883). Volume 1 appeared (in German) in 1867, and the two subsequent volumes appeared at later dates after the author's death - completed from extensive notes left by Marx himself.

Published in 1894, 11 years after the death of Marx himself, Capital Volume 3 was the product of the untiring and meticulous work of Friedrich Engels working from Marx’s outline and notes and carried the subtitle The Process of Capitalist Production as a Whole. In seven parts, Marx and Engels were determined to demonstrate that private property, competition and the market economy driven by the profit motive must lead to the demise of capitalism. 

The Communist Manifesto (1848), Marx and Engels' revolutionary summons to the working classes, is one of the most important and influential political theories ever formulated. After four years of collaboration the authors produced this incisive account of their idea of Communism, in which they envisage a society without classes, private property or a state. They argue that increasing exploitation of industrial workers will eventually lead to a revolution in which Capitalism is overthrown. 

Without question one of the most significant books in modern history, The Communist Manifesto is a brief, populist pamphlet that distils the core ideas of communism into accessible prose. Published just months before violent uprisings threatened to destabilise much of the European establishment, it outlines a view of history as a constant battle between the classes that will inevitably result in revolution.

Vladimir Ilyich Ulyanov (1870-1924) is better known by his alias Lenin. A Russian revolutionary, politician, and political theorist, he served as the head of government of Soviet Russia from 1917 to 1924 and of the Soviet Union from 1922 to 1924. Under his administration, Russia became the Soviet Union, a one-party state governed by the Communist Party.  

The Accumulation of Capital was published in 1913. In it, Rosa Luxemburg set out to take the views of Karl Marx further by arguing that capitalism can only exist when there are non-capitalist economies to exploit. She postulates that capitalism would stagnate were there no non-capitalist countries with economic resources to assimilate by a cruel, exploitative process of destabilising natural and peasant economies.  

In 1965, the US government helped the Indonesian military kill approximately one million innocent civilians. This was one of the most important turning points of the 20th century, eliminating the largest communist party outside China and the Soviet Union and inspiring copycat terror programs in faraway countries like Brazil and Chile. But these events remain widely overlooked, precisely because the CIA's secret interventions were so successful.

As one of the first titles in Atlantic Monthly Press' "Books That Changed the World" series, America's most provocative satirist, P.J. O'Rourke, reads from Adam Smith's revolutionary The Wealth of Nations - so you don't have to. Recognized almost instantly on its publication in 1776 as the fundamental work of economics, The Wealth of Nations was also recognized as really long: the original edition totaled over 900 pages in two volumes.

First published in 1936, Keynes’ ideas had evolved during the difficulties following World War 1 in Europe, and the US crash and the Depression of the 1920s-'30s and the misery of mass unemployment. He deplored the situation where a few individuals or companies stored massive wealth while vast numbers experienced poverty and insecurity (his alarm bells ring today!) and sought to promote initiatives where governments could intervene with social projects to keep money fluctuating.  

What are the grand dynamics that drive the accumulation and distribution of capital? Questions about the long-term evolution of inequality, the concentration of wealth, and the prospects for economic growth lie at the heart of political economy. But satisfactory answers have been hard to find for lack of adequate data and clear guiding theories.
