The failure of the campaign seemed to show the Republic's remarkable stability. But the propaganda that for months had attempted to tarnish the reputation of parliamentary democracy permanently altered the political culture. Changes began to take place on the political right that ultimately led to the weakening of its more conservative forces in favor of the NSDAP. Just how unstable the Republic was became apparent only a few months later with the onset of the
Great Depression, the subsequent rise of the NSDAP and the final erosion of parliamentary democracy. One of Hugenberg's core goals was to use the campaign against the Young Plan to bring the political right together. This goal failed with the breakup of his own party and the founding of the People's Conservative Association, out of which grew the short-lived Conservative People's Party and the
Christian Social People's Service. In the
Reichstag election of 1930, the Protestant conservative right was fragmented, and the DNVP received only 7% of the vote. The party's closeness to the NSDAP, which had been emphasized during the campaign, made the formation of a middle-class bloc including the DNVP impossible. It marked the beginning of a development that contributed to the decline of the middle-class parties as a whole. in 1945. In retrospect the NSDAP appears to have been the real winner. At the end of 1929 and the beginning of 1930, it made gains in the state parliamentary elections in
Baden and
Thuringia as well as in the civic elections in
Lübeck. In January 1930
Wilhelm Frick in Thuringia became Germany's first NSDAP minister. In the 1930 Reichstag election, the party's representation increased from 2.6% to 18.3%. With its participation in the Reich Committee, the NSDAP succeeded in breaking its previous political isolation. For the first time since 1923 Hitler played a significant role in German politics. A considerable body of research argues that Hitler's participation made him a potential alliance partner for the middle class political right. During the campaign and afterwards, the NSDAP received large amounts of money from industry, and that, the research says, played a significant role in the party's success in the Reichstag elections of 1930. In addition, the Hugenberg press was from then on at Hitler's disposal. The direct effect of the campaign on the rise of the NSDAP is, however, disputed. Historian Otmar Jung in particular warned against overestimating it. According to his view, participation in the referendum in itself played only a minor role in the rise of the NSDAP. Participation in the Reich Committee was associated with little money or additional propaganda opportunities for the party. Others do not see this so conclusively. According to
Eberhard Kolb, the NSDAP was certainly able to draw on the financial resources of the Reich Committee. That made it possible for them, in the midst of the anti-Young Plan campaign, to organize the largest party congress to date with 200,000 participants and to uniform 20,000 SA men in September 1929. Historian Gerhard Schulz early on emphasized that Hitler had succeeded in shaping his cooperation in such a way that he did not come across as an opportunist and could continue to be seen as a revolutionary radical. The NSDAP became both a partner and a rival for the still powerful traditional right, especially the
Stahlhelm. The party's strategy was to avoid permanent ties to other groups. On the other hand, it was open to short term alliances if they contributed to its own strengthening. In light of the campaign against the Young Plan,
Josef Stalin demanded in September 1929 that the
Communist Party of Germany (KPD) take a fundamentally different position on the reparations issue. He saw the campaign as the key to the NSDAP's sudden success. There were still reservations in the
Comintern about a turn towards a nationalist-populist position, but they ended in 1930 in the face of further successes by the NSDAP. In August of that year, the KPD newspaper
Die Rote Fahne published a "Program Declaration for National and Social Liberation" in which the party used strongly nationalist language. The attempt to draw protest voters away from the NSDAP with national slogans failed. In the 1930 Reichstag election, the KPD barely made gains, while the NSDAP leapfrogged them by adding 95 seats. == Results ==
