In 1983/1984, Psycho/Danger was the one who first suggested the name Assassin. In Anglo-American terms, Assassin means a “politically motivated murderer”. The Assassins (arabic “Hashish consumers”. French = “murder”) were members of a political, Islamic, Shiite secret organization in 11A.D. who also acted in their own self interest for power. Disliked kings and leaders were kidnapped or assassinated and the reward for the “soldiers” was hashish which gave them a euphoric feeling of paradise which was a strong motivator for each Assassin.
The band chose “Assassin” as it's band name for it's shock value, the threatening nature of the word and it being easy for metalheads to remember. Another good reason was that Assassin starts with “A” so in alphabetically arranged lists, Assassin is always mentioned in the beginning.
Unknown to the band at the time, there were already two American bands in the early 80s who were also called “Assassin”. Subsequently, it was found out that there were more bands that existed with the same name.
A French rap band and a glam metal band from Taiwan to name a couple.
