Which Assassin's Creed protagonist is known as Ezio Auditore da Firenze?

Ezio Auditore da Firenze is the Assassin's Creed protagonist known by that name.

Ezio is the central historical character of Assassin's Creed II, Assassin's Creed: Brotherhood, and Assassin's Creed: Revelations. His story begins in Renaissance Florence, where the execution of members of his family leads him into the Assassin Brotherhood.

Across the trilogy, Ezio travels through several Italian cities, including Florence, Venice, and Rome. He later journeys to Constantinople while searching for Altaïr's legacy. The games portray his development from a young nobleman into a senior mentor.

Ezio is sometimes mistaken for Altaïr because both are major early protagonists, but they belong to different historical periods. Altaïr's story is set mainly during the Third Crusade, whereas Ezio's principal adventures span the late fifteenth and early sixteenth centuries.
