From the old Arabic word "hashshshin," which meant, "someone who is addicted to hash," that is, marijuana. Originally refered to a group of warriors who would smoke up before battle.

They supposedly were a secret society (a la the FreeMasons) which was influential in every middle eastern court from Persia to Bangladesh. They were supposedly a brotherhood of assasins, devoted to their caballa and its secrecy, protected by an unlimited number of fanatical followers and unlimited material wealth. Assassination was their favorite method of instituting their power (see the Zoroastrian lore of the eunich priest Arachmenes and his assistance to Darius and Xerxes in their rise to/fall from power).
