In Assassin's Creed Odyssey, which ancient Greek war provides the main historical backdrop?

The Peloponnesian War provides the main historical backdrop for Assassin's Creed Odyssey. The conflict between Athens and Sparta lasted from 431 to 404 BCE, with shifting alliances and battles across the Greek world.

Odyssey is set in the fifth century BCE and allows the player to choose either Kassandra or Alexios as the playable character. The protagonist becomes involved in family, political, and mercenary conflicts while traveling through ancient Greece.

The game includes historical figures and locations associated with the period, but its plot is fictional and should not be treated as a complete historical account. The Greco-Persian Wars occurred earlier, while the Macedonian Wars and Punic Wars belong to later periods. These neighboring conflicts can cause confusion when identifying Odyssey's central historical setting.
