What is the name of the Assassin Order's creed in the Assassin's Creed series?

The Assassin Order's creed is “Nothing is true; everything is permitted.”

The phrase expresses the fictional order's emphasis on skepticism, personal responsibility, and freedom of action. It is presented as a guiding maxim rather than a simple permission to behave without consequences. Assassins are still expected to follow rules such as avoiding harm to innocents and maintaining secrecy.

The creed is associated with the historical Nizari Ismaili tradition in the series' fictionalized interpretation, while the modern games place it within the long conflict between Assassins and Templars. Characters repeat or discuss the words across many eras of the franchise.

“Requiescat in pace” is strongly associated with Ezio Auditore, but it is a phrase he says to people he has defeated, not the Assassin Order's creed. That distinction is a frequent source of confusion.
