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.
Joseph Stalin
Stalin faced problems in his family life. In 1929, his son Yakov unsuccessfully attempted suicide; his failure earned Stalin's contempt. His relationship with Nadya was also strained amid their arguments and her mental health problems. In November 1932, after a group dinner in the Kremlin in which Stalin flirted with other women, Nadya shot herself.
Publicly, the cause of death was given as appendicitis; Stalin also concealed the real cause of death from his children. Stalin's friends noted that he underwent a significant change following her suicide, becoming emotionally harder.
