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.
Night of the Murdered Poets
Stalin continued his oppression of Jews with the Doctors' Plot. Weeks after Stalin's death, on March 5, 1953, the new Soviet leadership renounced the Doctors' Plot, which led to questions about the similar situation with the JAC defendants. Upon the discovery that much of the testimony from the trial was the result of torture and coercion, the proceedings were reexamined. On November 22, 1955, the Military Collegium of the Supreme Court of the USSR determined that there was "no substance to the charges" against the defendants and closed the case.
