Chabad (Hebrew: חב"ד), also known as Lubavitch or Chabad Lubavitch, is a large sect of Hasidic (Ultra-Orthodox) Judaism. Followers (known as Chabadniks) believe their late Rebbe, Menachem Mendel Schneerson, was the promised "Mosiach", even though he didn't do anything the Jewish Messiah is supposed to do before his death. This is still okay because, of course, the good Rebbe will be coming back to finish the job any day now... any day now. Just you wait.
In the interim, Chabadniks believe that the Rebbe is still spiritually present with them, so if they perform rituals for him, he will work miracles in their lives. They are also big into doing "kiruv" (outreach) to unaffiliated Jews in the hopes that they will join them, and to this end have set up Chabad Houses staffed with their rabbis everywhere from Anchorage to Auckland. When humans land on Mars, rumour has it a Chabad House will be there to greet them.
Now, don't let the whole end-times messianic gobbledygook and aggressive proselytizing fool you, Chabad is completely, 110%Christ-- err, Jewish. Absolutely nothing questionable about the fact that they worship a dead guy, even though Judaism prohibits idol worship. Not at all. Well, actually more than a few Jews consider it a cult, even akin to Mormonism, especially since those who try to leave are often shunned.
Chabad is an acronym formed from three separate Hebrew words - Chokmâh (חכמה, 'wisdom'), Binah (בינה, 'understanding'), and Da'at (חכמה, 'knowledge'). The name Lubavitch derives from the Russian town in which the now-dominant line of leaders resided from 1813 to 1915.
Since 1951, Chabad began conducting large-scale outreach to unaffiliated Jews around the world, establishing synagogues and "Chabad centres" in countries around the world. These centres can be found in remote areas such as Noumea, New Caledonia, where we can safely say there are very few Jews. However, these centres accommodate Jewish tourists.
Chabad's website is also one of the largest websites dealing in Jewish theology, beliefs and rituals, which creates an interesting scenario in which the main source of information on a diverse faith such as Judaism comes from one of its most fundamentalist sects.
Chabad is split between "Moderate" and "Fundamentalist" factions, in particular over Chabad Messianism. Fundamentalists believe that the Rebbe himself is still alive and the messiah, though he died in 1994 at the age of 92. Moderates within the movement refute this claim, while still believing that the Messiah is inevitable. The tensions between these factions have led to various splits within Chabad, and the issue is quite controversial.
In 1978, the Rebbe's birthday, 11 Nissan on the Hebrew Calendar, was recognized as "Education Day USA". Schneerson supported the creation of the Department of Education, and believed that Education built a strong emphasis on moral and ethical values. He also believed in promoting a just world, and human rights for all people. While generally accommodating to Orthodox views on women, as he was no feminist, he broke with tradition and taught Torah to women and girls. He encouraged Women to speak their mind and to learn, believing it to be for the greater good.
