Socialism as a power in Europe may be said to begin with Marx. It is true that before his time there were Socialist theories, both in England and in France. It is also true that in France, during the revolution of 1848, Socialism for a brief period acquired considerable influence in the State. But the Socialists who preceded Marx tended to indulge in Utopian dreams and failed to found any strong or stable political party. To Marx, in collaboration with Engels, are due both the formulation of a coherent body of Socialist doctrine, sufficiently true or plausible to dominate the minds of vast numbers of men, and the formation of the International Socialist movement, which has continued to grow in all European countries throughout the last fifty years. In order to understand Marx's doctrine, it is necessary to know something of the influences which formed his outlook. He was born in 1818 at Treves in the Rhine Provinces, his father being a legal official, a Jew who had nominally accepted Christianity. Marx studied jurisprudence, philosophy, political economy and history at various German universities. In philosophy he imbibed the doctrines of Hegel, who was then at the height of his fame, and something of these doctrines dominated his thought throughout his life. Like Hegel, he saw in history the development of an Idea. He conceived the changes in the world as forming a logical development, in which one phase passes by revolution into another, which is its antithesis--a conception which gave to his views a certain hard abstractness, and a belief in revolution rather than evolution. But of Hegel's more definite doctrines Marx retained nothing after his youth. He was recognized as a brilliant student, and might have had a prosperous career as a professor or an official, but his interest in politics and his Radical views led him into more arduous paths. Already in 1842 he became editor of a newspaper, which was suppressed by the Prussian Government early in the following year on account of its advanced opinions. This led Marx to go to Paris, where he became known as a Socialist and acquired a knowledge of his French predecessors.[1] Here in the year 1844 began his lifelong friendship with Engels, who had been hitherto in business in Manchester, where he had become acquainted with English Socialism and had in the main adopted its doctrines.[2] In 1845 Marx was expelled from Paris and went with Engels to live in Brussels. There he formed a German Working Men's Association and edited a paper which was their organ. Through his activities in Brussels he became known to the German Communist League in Paris, who, at the end of 1847, invited him and Engels to draw up for them a manifesto, which appeared in January, 1848. This is the famous ``Communist Manifesto,'' in which for the first time Marx's system is set forth. It appeared at a fortunate moment. In the following month, February, the revolution broke out in Paris, and in March it spread to Germany.
