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 initiated all key decisions during the Terror, personally directing many of its operations and taking an interest in their implementation. His motives in doing so have been much debated by historians. His personal writings from the period were — according to Khlevniuk — "unusually convoluted and incoherent", filled with claims about enemies encircling him. He was particularly concerned at the success that right-wing forces had in overthrowing the leftist Spanish government, fearing a domestic fifth column in the event of future war with Japan and Germany. The Great Terror ended when Yezhov was removed as the head of the NKVD, to be replaced by Lavrentiy Beria, a man totally devoted to Stalin. Yezhov was arrested in April 1939 and executed in 1940. The Terror damaged the Soviet Union's reputation abroad, particularly among sympathetic leftists. As it wound down, Stalin sought to deflect responsibility from himself, blaming its "excesses" and "violations of law" on Yezhov.
