Karl Marx was a German philosopher, sociologist, economic historian, journalist, and revolutionary socialist who developed the socio-political theory of Marxism. He was born on May 5 1818 in a town located in the Kingdom of Prussia's Province of the Lower Rhine. During his childhood, he was privately educated until 1830, then he entered Trier High School, whose headmaster Hugo Wyttenbach was a friend of his father. In 1835, Karl Marx aged seventeen, began to attend the University of Bonn, where he wished to study philosophy and literature. But he was able to avoid military service when he turned eighteen because he suffered from a weak chest. From considering an academic career, Marx turned to journalism. He moved to the city of Cologne in 1842, where he began writing for the radical newspaper Rheinische Zeitung, where he expressed his increasingly socialist views on politics. On June.19 1843, Karl Marx married Jenny von Westphalen after seven year waiting at the Pauluskirche in Bad Kreuznach. On September of 1844, he and Engels began to research the socialist, and soon became best friends. In 1845 Marx and Engels visited the leaders of the Chartists, a socialist movement in Britain, using the trip as an opportunity to study in various libraries in London and Manchester. In 1848, hoping to see the revolution spread to Germany, Marx moved back to Cologne where he began issuing a handbill entitled the Demands of the Communist Party in Germany. Marx moved to London in May 1849 and would remain in the city for the rest of his life. It was here that he founded the new headquarters of the Communist League, and got heavily involved with the socialist German Workers' Educational Society. In 1864 Marx became involved in the International Workingmen's Association. He became a leader of its General Council, to whose General Council he was elected at its inception. During the last decade of his life, Marx's health declined and he became incapable of the sustained effort that had characterized his previous work. He did manage to comment substantially on contemporary politics, particularly in Germany and Russia. Unfortunately, following the death of his wife Jenny in December 1881, Marx developed a catarrh that kept him in ill health for the last 15 months of his life. It eventually brought on the bronchitis and pleurisy that killed him in London on 14 March 1883. Within 25 years of his death, the continental European socialist parties that acknowledged Marx's influence on their politics were each gaining. （http://en.wikipedia.org/wiki/Karl_Marx）
Karl Marx was born in a lawyer family, his ancestry was Jewish. His maternal grandfather was a Dutch rabbi. His grandfather was Rabbin Marc Levy, a Jewish law jurist. Karl's father, Herschel Marx, was middle-class and relatively prosperous, owning a number of Moselle vineyards; he converted from Judaism to the Protestant Christian denomination of Lutheranism prior to his son's birth, taking on the German forename of Heinrich over Herschel. His wife was Jenny von Westphalen, a beautiful baroness of the Prussian ruling class—"the most desirable young woman in Trier” —who broke off her engagement with a young aristocratic second lieutenant in order to be with him. Later they had six children. (Francis Wheen. “Karl Marx a life” 1999)
