Zaidiyyah
Zaidiyyah or Zaidism (Arabic: الزيدية‎ az-zaydiyya, adjective form Zaidi or Zaydi; occasionally known as Fivers) 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. Followers of the Zaydi Islamic jurisprudence are called Zaydi and make up about 50% of Muslims in Yemen, with the vast majority of Shia Muslims in that country being Zaydi.
