Capital: A Critique of Political Economy 

A book written by Karl Marx and published in 1867 that deals with the development of capitalism and its problems. It is generally highly admired for its foresight of how capitalism would eventually develop over time.

Note that Capital: A Critique of Political Economy is purely criticizing the status quo, predicting its development and pinpointing its problems, while the Manifesto of the Communist Party (or simply Communist Manifesto) offers possible solutions to these problems.

'Hey, I just read Capital: A Critique of Political Economy by Karl Marx. And I now believe that the only way to create a fair society is by overthrowing the bourgeoisie.'
