In October 1964, Khrushchev was deposed by a joint Central Committee and Politburo plenum and succeeded by another collective leadership, this time led by Leonid Brezhnev, born in Ukraine, as First Secretary and Alexei Kosygin as Chairman of the Council of Ministers. Brezhnev's rule would be marked by social and economic stagnation, a period often referred to as the Era of Stagnation. The new regime introduced the policy of "rastsvet", "sblizhenie" and "sliianie" ("flowering", "drawing together" and "merging"/"fusion"), which was the policy of uniting the different Soviet nationalities into one Soviet nationality by merging the best elements of each nationality into the new one. This policy turned out to be, in fact, the reintroduction of the russification policy. The reintroduction of this policy can be explained by Khrushchev's promise of communism in 20 years; the unification of Soviet nationalities would take place, according to Vladimir Lenin, when the Soviet Union reached the final stage of communism, also the final stage of human development. Some all-Union Soviet officials were calling for the abolition of the "pseudosovereign" Soviet republics, and the establishment of one nationality. Instead of introducing the ideologic concept of the "Soviet Nation", Brezhnev at the 24th Party Congress talked about "a new historical community of people – the Soviet people", and introduced the ideological tenant of Developed socialism, which postponed communism. When Brezhnev died in 1982, his position of General Secretary of the Communist Party of the Soviet Union was succeeded by Yuri Andropov, who died quickly after taking power. Andropov was succeeded by Konstantin Chernenko, who ruled for little more than a year. Chernenko was succeeded by Mikhail Gorbachev in 1985.
