Azali

Azali, or Azali Bábí is a monotheistic religion and the name of a follower of Subh-i-Azal and the Báb. Early followers of the Báb were known as Bábís, however in the 1860s a split occurred after which the vast majority of Bábís followed Mirza Husayn `Ali, known as Bahá'u'lláh, and became known as Bahá'ís, while the minority who followed Subh-i-Azal came to be called Azalis.

Current estimates are that there are no more than a few thousand.
