Hashishin

The word “assassin” derives from “hashish”, referring to Nizari Ismailis, who operated out of Lebanon. They were a medieval sect of fanatical Muslims who only answered to a leader known as the “Old Man of the Mountains.” They had a penchant for covertly murdering many leaders of opposing forces after consuming large quantities of hashish. Hashishin (or “pot addict”) was a derogatory term applied to this sect by their enemies, as marijuana is outlawed under Islam.
