Which historical civilization provides the setting for Assassin's Creed Origins?

Ancient Egypt provides the historical setting for Assassin's Creed Origins.

The game takes place mainly in Egypt during the first century BCE, near the end of the Ptolemaic period. Its protagonist, Bayek of Siwa, is a Medjay who becomes involved in events that lead toward the formation of the Hidden Ones, the organization that later develops into the Assassin Brotherhood.

Origins explores locations such as Alexandria, Memphis, Siwa, and the Nile Valley. It also depicts the political world of Cleopatra VII and Julius Caesar, combining real historical figures and places with the franchise's fictional secret-history plot.

The title reflects the game's focus on the origins of the Assassin tradition. It is not set in Ancient Greece, which is the main historical environment of Assassin's Creed Odyssey. Origins also introduced major role-playing features, including equipment levels, skill trees, and dialogue choices.
