Death and state funeral of Joseph Stalin
On 5 March 1953, at 21:50 EET, Joseph Stalin, the second leader of the Soviet Union, died at the Kuntsevo Dacha aged 74 after suffering a stroke. After four days of national mourning, Stalin was given a state funeral and then buried in Lenin's Mausoleum on 9 March. Nikita Khrushchev, Georgy Malenkov, Vyacheslav Molotov and Lavrentiy Beria were in charge of organizing the funeral.
Active measures
Some of the active measures were undertaken by the Soviet secret services against their own governments or Communist rulers. Russian historians Anton Antonov-Ovseenko and Edvard Radzinsky suggested that Joseph Stalin was killed by associates of NKVD chief Lavrentiy Beria, based on the interviews of a former Stalin body guard and circumstantial evidence.
According to Yevgeniya Albats allegations, Chief of the KGB Vladimir Semichastny was among the plotters against Nikita Khrushchev in 1964. KGB chairman Yuri Andropov reportedly struggled for power with Leonid Brezhnev. The Soviet coup attempt of 1991 against Mikhail Gorbachev was organized by KGB chairman Vladimir Kryuchkov. Gen. Viktor Barannikov, then the former State Security head, became one of the leaders of the uprising against Boris Yeltsin during the Russian constitutional crisis of 1993.
