Chabad
The Chabad movement was started by Rabbi Schneur Zalman of Liadi in Eastern Europe during the late 1700s. He named his 'Chabad' because in Hebrew it is an acronym for Wisdom, Understanding, and Knowledge. 'Lubavitch' was the name of the town in Russia where the movement was at from the time of the second Lubavitcher Rebbe (leader), Rabbi Dov Ber Schneuri, through the sixth, Rabbi Joseph Isaac Schneersohn.
