Chabad philosophy in the context of "Chabad"

Chabad, also known as Lubavitch, Habad and Chabad-Lubavitch (US: /xəˈbɑːd luˈbɑːvɪtʃ/; Hebrew: חב״ד לובביץּ׳; Yiddish: חב״ד ליובאוויטש), is a dynasty in Hasidic Judaism. Belonging to the Haredi (ultra-Orthodox) branch of Orthodox Judaism, it is one of the world's best-known Hasidic movements, as well as one of the largest Jewish religious organizations. Unlike most Haredi groups, which are self-segregating, Chabad mainly operates in the wider world and caters to nonobservant Jews.

Founded in 1775 by Rabbi Shneur Zalman of Liadi (1745–1812) in the city of Liozno in the Russian Empire, the name "Chabad" (חב״ד) is an acronym formed from the three Hebrew words—Chokmah, Binah, Da'at—for the first three sefirot of the kabbalistic Tree of Life after Keter: חכמה, בינה, דעת, "Wisdom, Understanding, and Knowledge"—which represent the intellectual and kabbalistic underpinnings of the movement. The name Lubavitch derives from the town in which the now-dominant line of leaders resided from 1813 to 1915. Other, non-Lubavitch scions of Chabad either disappeared or merged into the Lubavitch line. In the 1930s, the sixth Rebbe of Chabad, Rabbi Yosef Yitzchak Schneersohn, moved the center of the Chabad movement from Russia to Poland. After the outbreak of World War II, he moved the center of the movement to Brooklyn, New York, in the United States, where the Rebbe lived at 770 Eastern Parkway until the end of his life.
