In February 1946, Shepilov was appointed deputy head of the Propaganda and Agitation Department of the
Soviet Army's Main Political Directorate. On 2 August 1946 he became the head of the propaganda department of the main Communist Party daily
Pravda. In mid-1947, the head of the Propaganda and Agitation Department of the Communist Party Central Committee
Georgy Aleksandrov and his deputies were subject to public criticism for being insufficiently vigilant and removed from their positions. Shepilov was appointed deputy chief of the Department on 18 September 1947. Since the new department head,
Mikhail Suslov, had other responsibilities, Shepilov had almost complete control of the Department's day-to-day operations. While in Moscow, Shepilov—famous for his near-
eidetic memory, erudition and polished manners (reputedly, he could sing the whole of
Tchaikovsky's opera
The Queen of Spades from memory)—became an expert on Communist ideology and a protégé of
Joseph Stalin's chief of Communist ideology
Andrei Zhdanov. One of his first tasks was to assist Zhdanov in disciplining the Soviet Union's two greatest living composers,
Dmitri Shostakovich and
Sergei Prokofiev. He selected Shostakovich's
Eighth and
Ninth Symphonies and Prokofiev's opera
War and Peace as the worst examples of what was wrong with Soviet music. The appointment of
Yuri Zhdanov, Andrei Zhdanov's son, to lead the Propaganda Department's Science Sector on 1 December 1947 put Shepilov in the delicate position of supervising his patron's son. The situation was made even more delicate by the fact that Yuri Zhdanov had just married Joseph Stalin's daughter Svetlana and the fact that Andrei Zhdanov, Stalin's closest advisor at the time, had many enemies in the Soviet leadership. When in April 1948 Shepilov approved Yuri Zhdanov's speech critical of Soviet biologist and Stalin favorite
Trofim Lysenko, it started an intense political battle between Andrei Zhdanov on the one hand and his rivals who were using the episode to discredit Zhdanov. On 1 July 1948, Zhdanov's main rival,
Georgy Malenkov, took over at the Communist Party Secretariat while Zhdanov was sent on a two-month vacation, where he died. Shepilov, however, not only survived this change at the top, but even improved his position and was appointed as the next head of the Propaganda and Agitation Department on 10 July 1948. He also survived the next round of the intra-Party struggle associated with the removal and later execution of the
Politburo member
Nikolai Voznesensky. However, on 14 July 1949, he was censured by the Central Committee for allowing the Party's main theoretical magazine
Bolshevik to publish Voznesensky's book on economics back when Voznesensky was still in power. In 1952 Stalin put Shepilov in charge of writing a new Soviet economics textbook based on Stalin's recently published
treatise Economic Problems of Socialism in the USSR. On 18 November 1952, after the 19th Communist Party Congress, Shepilov was appointed editor-in-chief of
Pravda. == Khrushchev's theoretician ==
