"The Nizari Ismailis were designated with a misnomer, Assassins in mediaeval Europe. This is an abusive term that had been given a wide currency by the Crusaders and their occidental chroniclers, who had first come into contact with the Syrian Ismailis in the Near East during the early decades of the 12th century. Charles E. Nowell writes in The Old Man of the Mountain that, "In the early years of the twelfth century, as the Christians spread their conquests in the holy land and Syria, they made the acquaintance of the Ismailis.

Mediaeval Europeans, who remained absolutely ignorant of Muslim beliefs and practices, had transmitted a number of tales, and produced a perverted image of the Ismailis.

It is certainly wrong to confound as do the Musulman doctors, in one common reprobation. And the Old Man of the Mountain himself was not so black as it is custom to paint him." In more recent times, too, many western scholars have continued to apply the ill-conceived term Assassins to the Nizari Ismailis without being aware of its etymology or dubious origin. Paul E. Walker makes his comments in his Abu Yaqub al-Sijistani: Intellectual Missionary (London, 1996, p. 1) that, "Until recently, however, the Ismailis were studied and judged almost exclusively on the basis of the evidence collected or fabricated by their enemies, including the bulk of the medieval Sunni heresiographers and polemicists who were hostile towards the Shi'is in general and the Ismailis among them in particular. These Sunni authors in fact treated Shi'ite interpretations of Islam as expressions of heterodoxy or even heresy. As a result, a
