Which historical era is the setting of Assassin's Creed Odyssey?

Ancient Greece is the historical setting of Assassin's Creed Odyssey.

The game takes place during the Peloponnesian War, a conflict between Athens and Sparta that began in 431 BC. Players explore a large version of the Greek world, including mainland regions and islands, while following a mercenary connected to the family of Leonidas I.

Odyssey was released in 2018 and is set several centuries before Assassin's Creed Origins. Its world includes historical figures such as Socrates, Pericles, and Alcibiades, alongside mythological elements presented through the series' fictional universe.

The two player-character options are Kassandra and Alexios, with Kassandra identified as the canonical protagonist in later franchise material. Ancient Egypt belongs to Origins, Renaissance Italy is central to Assassin's Creed II, and Victorian London is the setting of Syndicate.
