Constantinople was called Istanbul in the western version of Assassin’s Creed Revelations.
Revelations is set mainly in the Ottoman city commonly known today as Istanbul. The game follows an older Ezio Auditore as he searches for keys connected to Altaïr’s former headquarters in Masyaf. The story also includes playable sections featuring Altaïr and Desmond.
The game was released in 2011 and presents Istanbul’s districts, markets, harbors, and major landmarks during the early sixteenth century. Ottoman prince Suleiman appears as a historical character during the succession tensions surrounding his family.
The city’s naming history can create confusion. Constantinople remained a widely used historical name, while Istanbul became the official name of the city in 1930, long after the game’s period. Western marketing and dialogue for Revelations generally use Istanbul, so that is the expected answer rather than Constantinople.
