The arrest and subsequent release from prison for "counter revolutionary activity" of the sixth Lubavitcher Rebbe, Rabbi Yosef Yitzchak Schneersohn in 5687 (1927). The Rebbe staunchly endured deprivation and torture, physical and mental, in an event meant to destroy the Jewish Underground, and emerged from his ordeal miraculously alive and undaunted, his defiant stance entirely intact. He was able to continue leading the Jewish resistance, leadership continued by his son-in-law and successor, Rabbi Menachem M. Schneerson, and to lay the foundation, ultimately, of the current Jewish revival.
