Which historical period and region provide the setting for Assassin's Creed Origins?

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

The game is set mainly in Egypt during the final decades of the Ptolemaic Kingdom. Its story follows Bayek of Siwa, a Medjay, and Aya as they become involved in the origins of the Hidden Ones, the organization that develops into the Assassin Brotherhood.

Players travel through locations including Siwa, Alexandria, Memphis, and the Giza plateau. The world combines cities, deserts, farmland, tombs, and ancient monuments, reflecting the political and cultural variety of the period.

Ptolemaic Egypt was ruled by a Macedonian Greek dynasty founded after Alexander the Great's conquest. Cleopatra VII and Julius Caesar appear in the narrative, although the game dramatizes historical events for its fictional story.
