Zayd ibn Ali
He led an unsuccessful revolt against the Umayyad Caliphate, in which he died. The event gave rise to the Zaidiyyah sect of Shia Islam, which holds him as the next Imam after Ali ibn Husayn. 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 Ummayids.
