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

“Nothing is true, everything is permitted” is the Assassin Brotherhood's creed in the Assassin's Creed series.

The phrase expresses the Brotherhood's skepticism toward absolute authority and fixed assumptions. It does not mean that Assassins believe ordinary facts are literally nonexistent. Instead, it is presented as a warning that accepted systems, political claims, and moral justifications should be questioned.

The second half is not a simple declaration that Assassins may do anything without consequences. Within the series, the creed is connected to responsibility, judgment, and the need to protect human freedom. Characters interpret and debate its meaning across different historical periods.

“Requiescat in pace” is a phrase associated especially with Ezio Auditore's farewell to defeated enemies, not the Brotherhood's creed. The creed appears in multiple games, novels, and other franchise media, making it one of the series' best-known lines.
