Political rights do not originate in parliaments; they are, rather, forced upon parliaments from without.
And even their enactment into law has for a long time been no guarantee of their security.
Just as the employers always try to nullify every concession they had made to labor as soon as opportunity offered, as soon as any signs of weakness were observable in the workers' organizations, so governments also are always inclined to restrict or to abrogate completely rights and freedoms that have been achieved if they imagine that the people will put up no resistance.
Even in those countries where such things as freedom of the press, right of assembly, right of combination, and the like have long existed, governments are constantly trying to restrict those rights or to reinterpret them by juridical hair-splitting.
Political rights do not exist because they have been legally set down on a piece of paper, but only when they have become the ingrown habit of a people, and when any attempt to impair them will meet with the violent resistance of the populace.
Where this is not the case, there is no help in any parliamentary Opposition or any Platonic appeals to the constitution.

— Rudolf Rocker, Anarcho-Syndicalism: Theory & Practice, 1947
Carl also had a substantial library consisting of socialist literature of all colors.
Rocker was particularly impressed by the writings of Constantin Frantz, a federalist and opponent of Bismarck's centralized German Empire; Eugen Dühring, an anti-Marxist socialist, whose theories had some anarchist aspects; novels like Victor Hugo's Les Misérables and Edward Bellamy's Looking Backward; as well as the traditional socialist literature such as Karl Marx's Capital and Ferdinand Lasalle and August Bebel's writings.
Rocker became a socialist and regularly discussed his ideas with others.
His employer became the first person he converted to socialism.

Under the influence of his uncle, he joined the SPD and became active in the typographers' labor union in Mainz.
He volunteered in the 1890 electoral campaign, which had to be organized in semi-clandestinity because of continuing government repression, helping the SPD candidate Franz Jöst retake the seat for the district Mainz-Oppenheim in the Reichstag.
Because the seat was heavily contested, important SPD figures like August Bebel, Wilhelm Liebknecht, Georg von Vollmar, and Paul Singer visited the town to help Jöst and Rocker had a chance to see them speak.

In 1890, there was a major debate in the SPD about the tactics it would choose after the lifting of the Anti-Socialist Laws.
A radical oppositional wing known as Die Jungen (The Young Ones) developed.
While the party leaders viewed the parliament as a means of social change, Die Jungen thought it could at best be used to spread the socialist message.
Unwilling to wait for the collapse of capitalist society which Marxism predicted, they wanted to start a revolution as soon as possible.
Although this wing was strongest in Berlin, Magdeburg, and Dresden, it also had a few adherents in Mainz, among them Rudolf Rocker.
In May 1890, he started a reading circle, named Freiheit (Freedom), to study theoretical topics more intensively.
After Rocker criticized Jöst and refused to retract his statements, he was expelled from the party.
The same would happen to the rest of Die Jungen in October 1891.
Nonetheless, he remained active and even gained influence in the socialist labor movement in Mainz.
Although he had already encountered anarchist ideas as a result of his contacts to Die Jungen in Berlin, his conversion to anarchism did not take place until the International Socialist Congress in Brussels in August 1891.
He was heavily disappointed by the discussions at the congress, as it, especially the German delegates, refused to explicitly denounce militarism.
He was rather impressed by the Dutch socialist and later anarchist Ferdinand Domela Nieuwenhuis, who attacked Liebknecht for his lack of militancy.
Rocker got to know Karl Höfer, a German active in smuggling anarchist literature from Belgium to Germany
