Who is the first historical protagonist seen in Assassin's Creed Revelations?

The first historical protagonist seen in Assassin's Creed Revelations is Ezio Auditore da Firenze.

Revelations opens with Ezio in 1511, when he travels to Constantinople to pursue Altaïr's legacy and search for keys connected with the Masyaf library. Ezio remains the main playable historical character, while the story also returns to Altaïr's memories and includes Desmond's modern-day perspective.

This structure makes the game a conclusion to Ezio's trilogy and a bridge between two major Assassin characters. Constantinople, known today as Istanbul, provides the principal setting, with districts, markets, and political figures shaping the narrative.

A frequent mistake is naming Altaïr because his memories are important to the plot. However, the game's opening historical sequence and primary campaign follow Ezio. Revelations was released in 2011 and was originally available for PlayStation 3, Xbox 360, and Windows.
