Constantinople is the Ottoman capital Ezio visits in Assassin’s Creed Revelations.
The game follows Ezio Auditore in 1511 as he travels to Constantinople, the capital of the Ottoman Empire, seeking keys connected with Altaïr Ibn-La’Ahad’s legacy. The city provides the main setting for Ezio’s missions, investigations, and interactions with the local Assassin bureau.
Revelations also introduces Prince Suleiman, who later becomes Suleiman the Magnificent, and features the Ottoman succession conflict involving his uncles. Ezio works alongside characters including Yusuf Tazim, the leader of the Constantinople Assassins.
The game’s historical city is often called Istanbul in modern usage, but the title and period context commonly use Constantinople. Revelations was released in 2011 and concludes the principal Ezio trilogy while also returning to Altaïr’s story through playable sequences set in Masyaf.
