Zayd ibn Ali
Zayd ibn '
Alī (also spelled Zaid, Zayyed; 695–740) was the son of
Ali ibn Husayn, and great-grandson of 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.
In contrast, his elder brother, Muhammad al-Baqir, is the next Imam of the Twelver and Ismaili Shias.
Nevertheless, he is considered an important revolutionary figure by Shias and a martyr (shaheed) by all schools of Islam, Sunnis and Shias.
The calling for revenge for his death and for the brutal display of his body contributed to the Abbasid Revolution.
Zayd was a learned religious scholar.
Various works are ascribed to him, including "Musnad al Imam Zayd" (published by E. Grifinni as "Corpus Iuris di Zaid b. ʿAlī", also known as "Majmuʿ al-Fiqh"), possibly the earliest known work of Islamic law.
However, the attribution is disputed; these likely represent early Kufan legal tradition.
