 The names of the assassin and their victims were preserved in a roll of honor preserved in Alamut Castle, cited by Bernard Lewis.Most of the assassinations by the Nizaris took place during the first decades of their struggle, which helped them to create a local political power.This tactic caused resentment against them, and there is a correlation between the assassinations and subsequent massacres of the Nizaris; this tactic gradually declined and the later attributed assassinations are probably of local origination.
