In Assassin's Creed: Revelations, Constantinople is the main historic setting for Ezio's adventure.
Ezio Auditore travels to Constantinople, the capital of the Byzantine Empire, while searching for keys connected to Altaïr Ibn-La'Ahad's legacy. The city's districts include Constantin, Bayezid, Imperial, Galata, and Sultanahmet, giving the game a broad urban setting shaped by trade, politics, and religious architecture.
The game is set in the early sixteenth century, when Constantinople was under Ottoman rule. Its population and landmarks reflect the meeting of Byzantine, Ottoman, and wider Mediterranean cultures. Players encounter historical figures including Suleiman the Magnificent, who is still a prince during much of the story, and the Ottoman statesman Piri Reis.
Constantinople is sometimes confused with Rome because Rome is Ezio's principal setting in Assassin's Creed Brotherhood. Florence and Venice are especially important to Assassin's Creed II, but neither is the main city of Revelations.
