In Assassin's Creed Revelations, Şehzade Ahmet is the Ottoman prince secretly working with the Templars. Ahmet is presented as a contender for the Ottoman succession and becomes the hidden political antagonist behind much of the Constantinople storyline.
Ezio Auditore arrives in Constantinople while searching for Masyaf keys and becomes involved with the local Assassin Brotherhood. The Ottoman succession dispute provides the historical framework, with Ahmet's relationship to the Templars linking palace politics to the wider Assassin–Templar conflict.
The name can be confused with other Ottoman rulers and princes. Suleiman appears in the story as the young prince who later becomes Sultan Suleiman the Magnificent, while Selim and Bayezid are different members of the dynasty. Ahmet is the specific prince revealed as the Templar collaborator, making him distinct from the historical figures who also appear in the game.
