Published in 1848, at a time of political upheaval in Europe, Karl Marx and Friedrich Engels’ Manifesto for the Communist Party was at once a powerful critique of capitalism and a radical call to arms. It remains the most incisive introduction to the ideas of Communism and the most lucid explanation of its aims. Much of what Marx and Engels proposed continues to be at the heart of political debate in the 21st century. It is no surprise, perhaps, that The Communist Manifesto (as it was later renamed) is the second bestselling book of all time, surpassed only by The Bible.
