Karl Marx and Friedrich Engels, born in Prussia in the 19th Century, were German philosophers. Along with other Communists, they wrote The Communist Manifesto in London and translated it in to several other languages. It is regarded as the best work of literature regarding Communism and is still as important now as it has always been.
It's sad that this is written in such a way that it was. Although I appreciate it is 19th century language, it still made me feel a little bleak whilst reading. Despite this, it is still full of valid points, I just think one should perhaps take ones time and find a thicker book with an introduction and notes.
