Zaidiyyah

Zaidiyyah or Zaidism is one of the Shia sects closest in terms of theology to the Ibadi and Mutazila schools. Zaidiyyah emerged in the eighth century out of Shi'a Islam. Zaidis are named after Zayd ibn ʻAlī, the grandson of Husayn ibn ʻAlī and the son of their fourth Imam Ali ibn 'Husain.
