Bobov communities are found in the Williamsburg section of Brooklyn; in Monsey, New York; Los Angeles; Lakewood, New Jersey; Linden NJ; Montreal; Toronto; Antwerp; and London.

[1] While most of the early yeshivos (Talmudical academies) originated in Lithuania, the 19th century saw the opening of similar institutions in Poland.

His work was continued by his son, Grand Rabbi Ben Zion Halberstam, author of Kedushas Tzion.

The yeshiva, which was originally located at 184 Brooklyn Avenue, later moved to the nearby Borough Park neighborhood.

At his funeral it was publicly announced that his oldest son Naftali would succeed him as Rebbe, and his younger brother Ben Zion would serve as Rav Hatzair (assistant rabbi).

Naftali Zvi died on March 23, 2005[1] (12th of Adar II, 5765), at age 74, leaving a wife, two daughters, and two sons-in-law: Yehoshua Rubin, Rav of Bobov-45; and Mordechai Dovid Unger, Rebbe of Bobov-45.

After Naftali Tzvi Halberstam died in 2005, a dispute arose[9] among Bobover Hasidim as to who should attain the dynasty leadership.

[11] The matter of succession was brought before a beth din (religious court) in 2007, which ruled that Halberstam would be declared the fifth Rebbe of Bobov (אדמו"ר מבאבוב) with its headquarters on 48th Street in Borough Park,[12] while Unger would be Rebbe of Bobov-45 (אדמו"ר מבאבוב-45), located on 45th Street.

In Israel, Bobov-45 has branches in Jerusalem, Bnei Brak, Beit Shemesh, Ashdod, Elad, and Beitar Illit.
