Wittorf affair
The Wittorf affair was a political scandal that occurred in the Communist Party of Germany during the Weimar Republic in 1928. Chairman Ernst Thälmann was ousted from the KPD Central Committee when his close friend John Wittorf had embezzled from a party campaign fund and Thälmann tried to cover up the embezzlement. Joseph Stalin had Thälmann reinstated as KPD Chairman using the influence of Comintern, completing the Stalinization of the KPD and beginning a purge of moderates from the party.
Scandal
John Friedrich Wittorf, a member of the KPD's central committee, was caught having embezzled around 1,500 to 3,000 Reichsmarks from the KPD's campaign fund during the 1928 German federal election. KPD chairman Ernst Thälmann, who was a close friend and sponsor of Wittorf, knew about the embezzlement but, due to the upcoming election, concealed it for tactical reasons. At first, responsibility was blamed on Hugo Dehmel, a district treasurer not involved in the embezzlement. On 26 September 1928, after rumors of the embezzlement had been leaked to the press, the KPD central committee expelled Wittorf and three other Hamburg officials from the KPD. Thälmann was accused of covering up Wittorf's actions and relieved of his party responsibilities during a party investigation, effectively removing him as KPD Chairman.Stalin's intervention
Joseph Stalin, the leader of the Soviet Union, used his influence in the communist world to have Thälmann reinstated as KPD Chairman despite the scandal. Stalin had been looking to strengthen Thälmann, whom he viewed as an ally and loyal supporter for the left turn recently adopted at the Sixth World Congress of the Comintern. Stalin felt he could count on Thälmann to purge the KPD of both its right and moderate left wings. Stalin asked Vyacheslav Molotov for advice in handling the problem of Thälmann's ouster. In a telegraph to Molotov on 1 October 1928, Stalin acknowledged that Thälmann had made a huge mistake in covering up the embezzlement, but defended his motives, calling them "unselfish". He said Thälmann had been trying to spare the party a scandal, in contrast to the motives of Arthur Ewert and Gerhart Eisler, KPD central committee members who were in the Conciliator faction. Stalin felt they had placed their own interests over those of the party and the Comintern and saw in their actions "absolutely no mitigating circumstances".Stalin then intervened: On 6 October 1928, the Executive Committee of the Comintern passed a resolution expressing "complete political trust" in Thälmann, reversing the KPD's 26 September decision and calling on the KPD to "liquidate all factions within the party". Despite stubborn resistance from several prominent officials, the central committee of the KPD reinstated Thälmann as party chairman on 20 October 1928. This signaled the beginning of the KPD's purge of its right-wing and the moderate Conciliator faction.
