With the approach of the German army during World War I, Rabbi Sholom DovBer (Rashab) and his family left Lubavitch for the city of Rostov-on-Don.
One of the most famous chassidic melodies – Rostover Nigun – bears the name of this place. The Rebbe Rashab was fond of this niggun and often sang it as a preparation to his Torah or Chassidic discourses. This is a serious and deep melody, characterized by its deep soul searching expression.
Lubavitch was the seat of the Chassidic movement for 102 years, from the day when the Mitteler Rebbe settled there in the Cheshvan of 5574 (1813). Between the years 5676-5684 (1915-1923), the seat of the Chassidic movement moved to Rostov-on-Don.
