Bahram al-Da'i

Bahram al-Da'i (, "Bahram the da'i [missionary]") or Bahram of Astarabad was a 12th-century Persian Nizari Ismaili who was the Chief Da'i and leader of the Assassins in Syria from after 1113 through 1128. Although his attempt to establish a Nizari base in Damascus was unsuccessful, he had an important role in organizing Nizari presence in Northern and Southern Syria.

After the execution of his predecessor Abu Tahir al-Sa'igh and the uprooting of the Nizaris in Aleppo, Bahram was sent by Alamut Castle in an attempt to expand the Nizari base in Syria.

Nizari power in Aleppo began to decline as the Artuqid prince Belek Ghazi captured the city in 1123, who expelled the sect from the city in 1124. claims Toghtekin was responsible for the situation.
