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.
Excess mortality in the Soviet Union under Joseph Stalin
The massacre was prompted by NKVD chief Lavrentiy Beria's proposal to execute all captive members of the Polish officer corps, dated 5 March 1940, approved by the Politburo of the Communist Party of the Soviet Union, including its leader, Joseph Stalin. The number of victims is estimated at about 22,000.
