Baghdad is the real historical city that serves as the main setting for Assassin's Creed Mirage.
Released in 2023, Mirage follows Basim Ibn Ishaq as he develops from a street thief into a Hidden One. The game is set in ninth-century Baghdad during the Islamic Golden Age, with the round city and surrounding districts forming the core of its explorable world. Its historical period is commonly associated with the Abbasid Caliphate.
Mirage returns to a more focused stealth structure after several large open-world role-playing games. Basim is trained by Roshan and investigates the Order of the Ancients while moving through locations such as the Round City, Abbasiyah, and Karkh. Damascus belongs prominently to Altaïr's first game, while Constantinople is central to Revelations, making those cities plausible but incorrect alternatives.
