Probably the most important political document of the last century

It is hard to review something like The Communist Manifesto while remaining politically neutral but I think it is safe to say that The Communist Manifesto is among the most important political works published in the last few centuries, if not the most important.

Bearing that in mind then it is quite disappointing to see just how small it is. To compare to the capitalist (a term which Marx coined!) equivalent, The Wealth of Nations, the entire manifesto can fit inside one of its chapters. It's nowhere near as comprehensive and yet has shaped the ideas of nations. The brevity in The Communist Manifesto is likely to have contributed to the vast amount of schisms in communist ideology due to differing interpretations. 

With all that being said it does contain some ideas that are very interesting and ideas that would have been revolutionary at the time of it being published. When workers were made to work in dangerous conditions for countless hours every day with little breaks for paltry wages you can see why people would have liked Marx's ideas. In fact some of his ideas such as a free education for all are standard practice now. 

To what degree you enjoy this book really depends on your political beliefs. Either way it should be required reading if you're into politics at all as it's a very important document. If you want to understand Marx's ideas in better detail however I recommend you read Das Kapital.
