Born at Trèves in 1818, the son of a Christian Jew who had a high post in the civil service, Marx was sent to the University of Bonn, towards the end of the '30s, won a considerable reputation there in philosophy and jurisprudence, determined, like Lassalle, to devote himself to the academic profession, and seemed destined for an eminently successful career, in which his subsequent marriage with the sister of the Prussian Minister of State, Von Westphalen, would certainly have facilitated his advancement. But at the University he came under the spell of Hegel, and passed, step by step, with the Extreme Left of the Hegelian school, into the philosophical, religious, and political Radicalism which finally concentrated into the Humanism of Feuerbach. Just as he had finished his curriculum, the accession of Frederick William IV. in 1840 stirred a rustle of most misplaced expectation among the Liberals of Germany, who thought the day of freedom was at length to break, and who rose with generous eagerness to the tasks to which it was to summon them. Under the influence of these hopes and feelings, Marx abandoned the professorial for an editorial life, and committed himself at the very outset of his days to a political position which compromised him hopelessly with German governments, and forced him, step by step, into a long career of revolutionary agitation and organization. He joined the staff of the _Rhenish Gazette_, which was founded at that time in Cologne by the leading Liberals of the Rhine country, including Camphausen and Hansemann, and which was the organ of the Young Hegelian, or Philosophical Radical Party, and he made so great an impression by his bold and vigorous criticism of the proceedings of the Rhenish Landtag that he was appointed editor of the newspaper in 1842. In this post he continued his attacks on the Government, and they were at once so effective and so carefully worded that a special censor was sent from Berlin to Cologne to take supervision of his articles, and when this agency proved ineffectual, the journal was suppressed by order of the Prussian Ministry in 1843. From Cologne Marx went to Paris to be a joint editor of the _Deutsche Französische Jahrbücher_ with Arnold Ruge, a leader of the Hegelian Extreme Left, who had been deprived of his professorship at the University of Halle by the Prussian Government, and whose magazine, the _Deutsche Jahrbücher_, published latterly at Leipzig to escape the Prussian authority, had just been suppressed by the Saxon. The _Deutsche Französische Jahrbücher_ were published by the well-known Julius Froebel, who had some time before given up his professorship at Zürich to edit a democratic newspaper, and open a shop for the sale of democratic literature; who professed himself a communist in Switzerland, and had written some able works, with very radical and socialistic leanings, but who seems to have gone on a different tack at the time of
