, 22 February 1950 In 1947, Zaisser returned to Germany and joined the
Socialist Unity Party (SED). Zaisser's career took off rapidly soon afterwards, and by 1948 he was Minister of the Interior and Deputy Minister-President of
Saxony-Anhalt. From 1949 to 1954, Zaisser served as a representative in the
Volkskammer and in 1950 worked on military and tactical issues at the
Marx-Engels-Lenin-Stalin Institute, a facility to which very few non-Soviets had access. In 1950, Zaisser gained membership in East Germany's
Politburo and the
Central Committee of the SED, thus becoming one of the most powerful men in the country. In the same year, Zaisser was awarded the Karl Marx Medal and appointed Director of the
Ministry of State Security. Using his vast knowledge of intelligence work, Zaisser built the Stasi into a powerful organization. After the death of Soviet leader
Joseph Stalin on 5 March 1953, Moscow favored replacing East Germany's Stalinist party leader
Walter Ulbricht and considered Zaisser a potential candidate. However, the
workers' uprising, which was suppressed by the
Red Army on 17 June, led to a backlash. Alarmed by the uprising,
Lavrenty Beria, the
First Deputy Premier of the Soviet Union and head of the
Ministry of Internal Affairs, personally travelled from
Moscow to
East Berlin. He conferred with Wilhelm Zaisser and with Erich Mielke, his deputy, both of whom he had known since the early 1930s. During both conversations, Beria demanded to know why the Stasi had failed to recognize the extreme discontent of the population and inform the Party leadership, which could then have prevented the uprising by taking extremely repressive measures in advance. Both Zaisser and Mielke answered Beria's questions circumspectly, and were accordingly left in their posts. (center) and

coup d'état led by
Nikita Khrushchev and
Marshal Georgy Zhukov. Beria was tried on charges of 357 counts of
rape and
high treason. He was
sentenced to death and
shot by
Red Army Colonel-General Pavel Batitsky on 23 December 1953. Meanwhile, when the East German Politburo met on 8 July, it still seemed that Ulbricht would be deposed as Party General Secretary. While Zaisser conceded that the SED's whole Politburo was responsible for the "accelerated construction of socialism" and for the subsequent fallout. But he also added that to leave Ulbricht as Premier, "would be opposed catastrophic for the New Course". Zaisser introduced a motion to replace Ulbricht with
Rudolf Herrnstadt as First Secretary, and by the end of the meeting, only two Politburo members still supported Ulbricht's leadership:
Free German Youth League chief
Erich Honecker and Party Control Commission Chairman
Hermann Matern. Ulbricht only managed to forestall a decision then and there with a promise to make a statement at the forthcoming 15th SED CC Plenum, scheduled for later that month. However, in 1953 Zaisser was decorated with the
Order of Karl Marx. Ultimately, Zaisser and all other anti-Ulbricht members of the Politburo and the Central Committee were dismissed from all their other positions. Ulbricht particularly accused Zaisser of not using more of the repressive power of the
Stasi during the uprising of June 1953. Zaisser was stripped of all his posts, expelled from the SED, and classified as an
enemy of the people. ==Death and legacy==
