Advancement under Khrushchev

Brezhnev's patron Khrushchev succeeded Stalin as General Secretary, while Khrushchev's rival Georgy Malenkov succeeded Stalin as Chairman of the Council of Ministers. Brezhnev sided with Khrushchev against Malenkov, but only for several years. In February 1954, he was appointed second secretary of the Communist Party of the Kazakh SSR, and was promoted to General Secretary in May, following Khrushchev's victory over Malenkov. On the surface his brief was simple: to make the new lands agriculturally productive. In reality, Brezhnev became involved in the development of the Soviet missile and nuclear arms programs, including the Baykonur Cosmodrome. The initially successful Virgin Lands Campaign soon became unproductive and failed to solve the growing Soviet food crisis. Brezhnev was recalled to Moscow in 1956. The harvest in the years following the Virgin Lands Campaign was disappointing, which would have hurt his political career had he remained in Kazakhstan.

In February 1956 Brezhnev returned to Moscow and was made candidate member of the Politburo assigned in control of the defence industry, the space program including the Baykonur Cosmodrome, heavy industry, and capital construction. He was now a senior member of Khrushchev's entourage, and in June 1957 he backed Khrushchev in his struggle with Malenkov's Stalinist old guard in the Party leadership, the so-called " Anti-Party Group ". Following the Stalinists' defeat, Brezhnev became a full member of the Politburo. In May 1960, he was promoted to the post of Chairman of the Presidium of the Supreme Soviet, making him the nominal head of state, although the real power resided with Khrushchev as First Secretary of the Soviet Communist Party and Premier.
