8. Elimination of the distrust between town and country. Marx returned to Germany and established the _Neue Rheinische Zeitung_ in Cologne in 1848. Engels served as editor. Because of revolutionary activity, Marx was forced to leave Germany in 1849. He went to Paris and then to London, where he became a newspaper correspondent and where he lived until his death in 1883. In 1859, the _Kritik der politischen Oekonomie_ was published. It contains the essential principles of Marx’s system of thought. In 1864, Marx found the opportunity for which he had long been seeking, namely, to organize the workers of the world into one large association. On September 28, in St. Martin’s Hall, Marx in the presence of a vast concourse of people, he initiated the “International Workingmen’s Association.” The fundamental idea was to organize the societies of workingmen which have a common purpose, namely, the emancipation of the working classes, into a world or international union for co-operative purposes. The International proposes that governments shall put the interests of the working classes to the forefront of national concern, and subordinate the present attention they give to war, diplomacy, and national jealousies. In 1869, Marx, aided by Karl Liebknecht (1826–1900), Engels and others, organized in Germany the Social Democratic Labor Party. The movement which Lassalle had started became united with the Marxian movement, and in 1875 the German Social Democracy presented a united front to capitalism. Marx, Engels, Liebknecht, and Bebel are its best-known leaders. Bismarck was forced to acknowledge its power, and condescended to inaugurate a system of social insurance in order to appease its rank and file. In 1867, 1885, and 1895, the three volumes of _Das Kapital_ appeared, in chronological order.[XIV-5] By this work, _Capital_, Marx is known throughout the world. The style is laborious; the analyses are minute and in places difficult to follow. The method is historical. Marx analyzes social evolution. He traces the rise of capitalism from its humble beginnings to its autocratic fruition. In this development the instruments of capital showed a tendency to congregate in a decreasing number of hands. By this token it will be seen that the number of the propertyless ever increases. Likewise, their influence decreases. In this way, the proletariat is developed, a product of capitalism.
