The more immediate theoretical founder of social democracy, and for many years its leading representative, was Karl Marx, born in 1818 in Treves (Trier). The social position of his family in Germany was excellent. His father, a converted Jew, occupied a high position in the civil service. Marx studied law at the universities of Bonn and Berlin. In the latter place he became so much interested in philosophy that he abandoned law. The philosophy which he adopted was the Hegelian. He intended to become a professor, but was led into politics and journalism by the apparent dawn of freedom accompanying the succession of Frederick William IV. to the Prussian throne in 1840. He soon became editor-in-chief of the _Rhenish Gazette_ (_Rheinische Zeitung_), which had been founded by leading liberals, and began to criticise the government with what was then called unheard-of boldness. But he was so skilful in his expressions that the special censor of the press, who was sent from Berlin to Cologne to watch the paper, could find no cause for legal proceedings against him. Finally, government becoming weary of such attacks, and having then the power to do so, simply decreed that at the expiration of the first quarter-year of 1843 the paper should cease to appear.[171] The interest which Marx had begun to take in matters of government showed him the necessity of informing himself more fully on subjects of political economy. He went to Paris, accordingly, after the suppression of the _Rheinische Zeitung_, to study that science, thinking that France then afforded better advantages for that purpose. He was, no doubt, right in this, as the Germans have only lately become great in political economy. In Paris he continued to wage war with the pen on the Prussian government, and was banished from France in 1844 by Guizot, to please Prussia. Going to Brussels, he continued his economic studies, interested himself in the cause of the laborers, and in his writings at this time expressed views similar to those which he held at the time of his death. In 1847, in company with Friedrich Engels, he composed and published a manifesto of the communistic party, which closed with these words: “The communists scorn to conceal their views and purposes. They declare openly that their aims can be attained only by a violent overthrow of the existing social order. Let the ruling classes tremble before a communistic revolution. The proletarians have nothing to lose except their chains. They have a world to gain. Proletarians of all lands, unite!”
