Karl Marx was born in 1818 in Trier, Prussia. While attending university in Berlin he was influenced by the ideas of the philosopher Hegel and his critics, the Young Hegelians, but Marx eventually rejected both schools of thought. He quickly earned the reputation of a revolutionary and left Germany for Paris, where he met his lifelong friend and collaborator, Friedrich Engels. Together they wrote and published The Communist Manifesto, which was published in 1848, just before the first wave of revolutions in France. Marx returned to Germany but his radical activities led to expulsion, whereupon he moved to London. There, Marx and Engels collaborated on further works on economics and contemporary politics. Marx also wrote his major treatise, Das Kapital, but only the first volume was published in his lifetime. Marx died in poverty on March 14, 1883, and was buried in Highgate Cemetery.
