Chabad-Lubavitch is one of the world's larger and best-known Hasidic movements in Orthodox Judaism. it is based in the Crown Heights section of Brooklyn, New York. The name "Chabad" is a Hebrew acronym for "Wisdom, Understanding, and Knowledge".
The project covers the seven Chabad Admors (Hebrew for: Our Master, Teacher and Rabbi) and their family members. Their genealogy goes back to the Maharal of Prague, Rashi and King David of Israel.
Chabad was founded in the late 18th century by Shneur Zalman of Liadi. The Lubavitch branch takes its name from Lyubavichi, the Russian (now Belarus) town where the group was based until the early 20th century.
Chabad maintains institutions in around 950 cities around the world, and in the early 21st century there were an estimated 3,300 Chabad institutions around the world in 75 countries, providing outreach and educational activities for Jews through Jewish community centers, synagogues, schools and camps.
The goal of this project is to cleanup (merge and correct) these branches of the big tree, and to encourage managers of private profiles on these branches to go public.
