In the _Open Letter_ the guiding principles of the Social Democratic agitation of Lassalle are given with absolute clearness and decision: that the working men should form an independent political party—one, however, in which the political programme should be entirely subordinated to the great social end of improving the condition of their class; that the schemes of Schulze-Delitzsch[2] for this end were inadequate; that the operation of the iron law of wages prevented any real improvement under the existing conditions; that productive associations, by which, the workmen should secure the full product of their labour, should be established by the State, founded on universal suffrage, and therefore truly representative of the people. The Leipsic Committee accepted the policy thus sketched, and invited him to address them in person. After hearing him the meeting voted in his favour by a majority of 1300 against 7. A subsequent appearance at Frankfort-on-the-Main was even more flattering to Lassalle. In that as in most other towns of Germany the workmen were generally disposed to support Schulze and the Progressist party. Lassalle therefore had the hard task of conciliating and gaining a hearing from a hostile audience. His first speech, four hours in length, met at times with a stormy reception, and was frequently interrupted. Yet he gained the sympathy of his audience by his eloquence and the intrinsic interest of his matter, and the applause increased as he went on. When, two days afterwards, he addressed them a second time, the assembly voted for Lassalle by 400 to 40. It was really a great triumph. Like Napoleon, he had, he said, beaten the enemy with their own troops. On the following day he addressed a meeting at Mainz, where 700 workmen unanimously declared in his favour. These successes seemed to justify Lassalle in taking the decisive step of his agitation—the foundation of the Universal German Working Men’s Association, which followed at Leipsic on May 23, 1863. Its programme was a simple one, containing only one point—universal suffrage. ‘Proceeding from the conviction that only through equal and direct universal suffrage[3] can a sufficient representation of the social interests of the German working class and a real removal of class antagonisms in society be realised, the Association pursues the aim, in a peaceful and legal way, especially by winning over public opinion, to work for the establishment of equal and direct universal suffrage.’ Hitherto Lassalle had been an isolated individual expressing on his own responsibility an opinion on the topics of the day. He was elected President, for five years, of the newly founded Association, and was therefore the head of a new movement. He had crossed the Rubicon, not without hesitation and misgiving.
