  Zaydism, otherwise known as Zaydiyya or as Zaydī Shīʿism, is a branch of Shia Islam named after Zayd ibn ʿAlī. Followers of the Zaydī school of jurisprudence are called Zaydīs or occasionally Fivers. However, there is also a group called Zaydī Wāsiṭīs who are Twelvers (see below). Zaydīs constitute roughly 42–47% of the population of Yemen.
