In 1838, following accusations of having had informers murdered, the czar himself issued orders for the Rebbe's arrest. He spent 22 months in a Kyiv dungeon, before spending six more months in a prison in Kamenitz. He was released, without ever being charged or tried, on Shushan Purim. Hearing that the czar had ordered his re-arrest, the Rebbe fled to Kishinev (Moldova), then to Iasi (Romania) Austria, and then re-settled in Sadagora (Bukovina-Ukraine), where he founded a large synagogue and re-established his Hasidic court. He died ten years later, leaving six sons to continue his path. Each of them founded Hasidic dynasties in their own right.
