In Assassin's Creed II, what is the full name of the Italian Assassin who becomes the game's hero?

Ezio Auditore da Firenze is the Italian Assassin who becomes the hero of Assassin's Creed II.

Ezio begins the game as a young Florentine nobleman whose family is destroyed by a political conspiracy. His personal quest for justice gradually develops into a larger struggle against the Templars. Along the way, he learns the Assassin way, builds alliances, and travels through major Renaissance locations such as Florence, Venice, and Forlì.

The surname “da Firenze” identifies Ezio with Florence, the city where much of his early story unfolds. The game uses real historical figures, including Leonardo da Vinci, as allies or important supporting characters, while the fictional Assassin conflict is woven around documented Renaissance settings.

Ezio's storyline continues in Assassin's Creed: Brotherhood and Assassin's Creed: Revelations. These three games are often grouped as the Ezio trilogy. He is not the same character as Altaïr, although the two meet through the series' framing narrative and become connected by Assassin history.
