Chabad, also known as Lubavitch, Habad and Chabad-Lubavitch, (Hebrew: חב"ד) is an Orthodox Jewish, Hasidic movement. Chabad is today one of the world's best known Hasidic movements and is well known for its outreach. It is the largest Hasidic group and Jewish religious organization in the world.
Founded in 1775 by Rabbi Schneur Zalman of Liadi, the name "Chabad" (חב״ד) is a Hebrew acronym for Chochmah, Binah, Da'at (חכמה, בינה, דעת): "Wisdom, Understanding, and Knowledge", which represent the intellectual underpinnings of the movement. The name "Lubavitch" is the Yiddish name for the originally Belorussian village Lyubavichi, now in Russia, where the movement's leaders lived for over 100 years.
In 1951, Rabbi Menachem Mendel Schneerson became the seventh Rebbe of Chabad-Lubavitch, and he transformed it from a small Hasidic movement into the largest and most widespread Jewish movement in the world today. He established a network of more than 3,600 institutions that provide religious, social and humanitarian needs in over 1,000 cities, spanning more than 80 countries and all 50 American states. Chabad institutions provide outreach to unaffiliated Jews and humanitarian aid, as well as religious, cultural and educational activities at Chabad-run community centers, synagogues, schools, camps, and soup kitchens.
