In the Assassin's Creed series, which organization is the Assassins' main enemy?

The Templars are the Assassins' main enemy in the Assassin's Creed series.

The conflict is presented as an ideological struggle between two secret organizations. The Assassins generally defend human freedom and individual choice, while the Templars seek order and control, often believing that peace requires strong centralized authority. Their methods and motives vary across different historical periods, but this opposition remains the franchise's central conflict.

Both groups pursue Pieces of Eden, powerful artifacts created by the fictional First Civilization. These objects can affect minds, generate illusions, or produce other extraordinary effects. Templar plans frequently involve using them to control populations or reshape political power.

The series uses historical Templars as inspiration but does not present its fictional organization as an exact history of the medieval Order of the Temple. The Brotherhood later known as the Assassins also changes names across eras; in ancient Egypt, its predecessor is called the Hidden Ones.
