Al-Mu'ayyad Ahmad

Who is Al-Mu'ayyad Ahmad?

Al-Mu'ayyad Ahmad was an imam of the Zaydiyyah sect.

Al-Mu'ayyad Ahmad's ancestor in the tenth degree was the Twelver imam Hasan bin Ali. He was a disciple of Abu Abdallah al-Basri and the qa'i Abd al-Jabbar, and a learned expert on the Ahl al-Bayt concept. Al-Mu'ayyad Ahmad was accepted as imam in Gilan and Deylaman in Persia, and had connections with the Zaidi area of Yemen. After 1013, no local imam was appointed for many years in the Yemeni highland. In Zaidi historiography, al-Mu'ayyad Ahmad is sometimes listed as such, although he never visited Yemen. He died in Langa in Deylaman in 1020, being succeeded by his brother Abu Talib Yahya.
