The group was established in 1889 by Max Liebermann von Sonnenberg, already widely known in anti-Semitic circles thanks to his Antisemites' Petition of 1880, his establishment of a short-lived string of discussion clubs called the Deutscher Volksverein and his prominence in the Berlin movement. The party contested the 1890 Reichstag election with Max Liebermann von Sonnenberg gaining their only seat. He remained a member of the house until his death in 1911.
Ideology
The group was strongly influenced by the thoughts of Adolf Stoecker but sought to take his ideas further. Their programme of 1890 called for the "nullification of civil rights laws" as applied to Jews and for the passing of a new Jew law which would treat Jewish Germans as a new category of aliens. Its initial areas of activity were in Bochum and Erfurt. Vaguely anti-democratic, they sought the gradual elimination of parliament in favour of more of a trades-based system of representation, although these ideas were largely underdeveloped. The DSP also actively supported German colonial expansion, a common feature of contemporary German antisemitic rhetoric that emphasised economic autarky and lebensraum as bulwarks against the Jews. Wilhelm Lattmann, who represented the DSP in the Reichstag, became especially noted for pushing the party's imperialist agenda as well as his attacks on "race-mixing" in the colonies. They also supported protectionism for German artisans, merchants and farmers and were opposed to the free market.
Connections to other groups
Although he personally disapproved of party politics, Theodor Fritsch was nonetheless attracted to the group's positions on the Jews and reprinted DSP propaganda in his journals. Through Fritsch the group also became close to Paul de Lagarde and asked him to run as a candidate for the Reichstag in 1889, an invitation he declined. Fritsch would eventually split with the DSP, his occultist views being at odds with the DSP, which was firmly Christian in outlook. The DSP was very close to the German National Association of Commercial Employees, a white-collar workers union that was equally notorious for its anti-Jewish rhetoric. Willibald Hentschel, an influential writer who sought to promote the supremacy of the Aryan race, and who as such was subsequently seen as a progenitor of Nazism, served on the party's board of directors. Heinrich Pudor, the Volkish commentator and pioneer of nudism, was also loosely associated with the DSP, speaking at some of their functions. One of a number of anti-Semitic parties active at the time, it merged with the German Reform Party in 1894 to form the German Social Reform Party. This group was riven by splits and personality conflicts throughout its existence however and came to an end in 1900, when the DSP was re-established. Liebermann von Sonnenberg clashed in particular with Oswald Zimmermann, another leading figure in the merged group. Differences had also been partially political, with the DSP considered the least radical of the antisemitic parties, with Friedrich Lange considering it alone as one of the "parties of order" during a failed attempt to forge a united party of the right.
