Kiya Buzurg-Ummid

States People Centers Other Kiyā Buzurg-Ummīd[note 1] (Persian: کیا بزرگ امید; died 1138) was a dāʿī and the second ruler (da'i) of the Nizari Isma'ili State, ruling Alamut Castle from 1124 to 1138 CE (or 518—532 AH).

On 25 Rabīʿ II 518 (11 June 1124), a day before death of Ḥassan-i Ṣabbaḥ, Ḥassan appointed him his successor.

[2] As opposed to Hassan Sabbah, who is depicted as a revolutionary leader, the Ismaili sources depict Buzurg-Ummid as an administrator and a chivalrous lord (e.g. the story of him protecting his old enemy, emir Yaran-Qush Bazdar of Qazvin and his followers, who had fled to Alamut).

[4] Another change in the Nizari government during his rule was the decrease in the number of assassinations; the list include the Abbasid caliph Al-Mustarshid, a prefect of Isfahan, a governor of Maragha, a prefect of Tabriz, and a mufti of Qazvin.

[4] The text of a bedtime prayer, titled "Prayer in Bedtime" (دعا در هنگام خواب du'ā dar hingām-i khwāb) in Persian attributed to Kiya Buzurg Ummid, is preserved in a manuscript of the Institute of Ismaili Studies in London.
