Purim
There is a tale in the Hasidic Chabad movement that supposedly Joseph Stalin died as a result of some metaphysical intervention of the seventh Chabad leader, Rabbi Menachem Mendel Schneerson, during the recitation of a discourse at a public Purim Farbrengen. Stalin was suddenly paralyzed on 1 March 1953, which corresponds to Purim 1953, and died 4 days later. Due to Stalin's death, nationwide pogroms against Jews throughout the Soviet Union were averted, as Stalin's infamous doctors' plot was halted.
Rise of Joseph Stalin
Since his falling out with Stalin in 1928–1929, Bukharin had written an endless stream of letters of repentance and admiration to Stalin. However, Stalin knew that Bukharin's repentance was insincere, as in private Bukharin continued to criticize Stalin and seek out other opponents of Stalin (the NKVD wiretapped Bukharin's telephone). Shortly before their executions in August 1936, Kamenev and Zinoviev had denounced Bukharin as a traitor during their show trial. At the December 1936 plenum of the Central Committee, Yezhov accused Bukharin and Alexei Rykov of treachery. Bukharin confessed to conspiring against Stalin, and was executed on 15 March 1938, on the same day that former NKVD chief, Yagoda, was also executed.
