maneuvers. To keep the government in office, Hindenburg pressured Seeckt to resign. His successor was Wilhelm Heye. The Social Democrats shifted their stance and were willing to join a centrist government, which would strengthen it. Hindenburg was agreeable. But then the socialists demanded a completely new cabinet, which the government rejected, consequently the Reichstag voted no confidence after oratory that made much of the secret collaboration between the Reichswehr and the Red Army, which had been revealed in British newspapers. To counter these attacks the Reichswehr relied on Colonel Kurt von Schleicher, who had served with Oskar in the Third Guards and was often a guest at the Palace. He assiduously strove to improve relations with the Republic. Again Hindenburg was saddled with finding a new government. He asked Marx to bring in more parties. The German Nationals agreed to join, and a new government was in place on 31 January 1927. It legislated the eight hour day and unemployment insurance. On 18 September 1927 Hindenburg spoke at the dedication of the massive memorial at Tannenberg, outraging international opinion by denying Germany's responsibility for initiating World War I, thereby repudiating Article 231 of the Treaty of Versailles. He declared that Germany entered the war as "the means of self-assertion against a world full of enemies. Pure in heart we set off to the defence of the fatherland and with clean hands the German army carried the sword." His words were much stronger than in the draft approved by Stresemann. The Allied governments retaliated by not congratulating him on his eightieth birthday. (He was more upset by Ludendorff's refusal to have any contact at the ceremony.) Most Germans did celebrate his birthday: his present was Neudeck, the ancestral East Prussian estate of the Hindenburgs, purchased with funds from a public subscription. Later it became known that the title was in Oskar's name, to avoid potential inheritance tax. A financial scandal in the navy led to the resignation of the defense minister. As his replacement, Schleicher wanted Groener, whose chief-of-staff he had been late in the war. The right strongly opposed him, but the Reichstag approved. Groener in turn enhanced Schleicher's role in the army. The Reichstag's four-year term was coming to an end, so Hindenburg pressed it to promptly pass required legislation and then dissolved it on 31 March 1928. His leadership was widely applauded.
