Agudas Chasidei Chabad was established by the sixth Lubavitcher Rebbe, Rabbi Yosef Yitzchok Schneersohn in 1923.

The founding meeting was in the early spring (27 Nisan), attended by about ten Lubavitcher Chassidim.

In March 1940, Schneersohn escaped Europe and immigrated to the United States, though he was unable to bring his library with him.

The library, now overseen by Rabbi Shalom Dovber Levine, holds over 250,000 volumes..[5][6] In 2010, a New York judge ruled in favor of Agudas Chasidei Chabad, deciding over an ownership dispute between the organization and the Gabbayim of the synagogue housed at 770 Eastern Parkway.

The court ordered the Gabbayim to deliver possession of the premises of 770 Eastern Parkway to Agudas Chasidei Chabad.
