Zayd ibn ʿAlī, also spelled Zaid, was the son of Ali ibn al-Husayn Zayn al-Abidin, and great-grandson of Ali ibn Abi Talib.

Zayd ibn Ali is also seen as a major religious figure by many Sunnis and was supported by the prominent Sunni jurist, Abu Hanifa, who issued a fatwa in support of Zayd against the Umayyads.
Zaydism is a branch of Shia Islam that emerged in the eighth century following Zayd ibn Ali‘s unsuccessful rebellion against the Umayyad Caliphate. In contrast to other Shia Muslims of Twelver Shi'ism and Isma'ilism, Zaydis, also sometimes incorrectly called Fivers, consider Zayd to be the Imam to whom obedience is obligatory, due to him being a patrilinial descendent of Fatima and making the Call (Dawah) to jihad, two necessary qualities for an Imam of Obedience for the Zaydis.
