In Assassin's Creed II, what is the full name of the Renaissance assassin who becomes the game's protagonist?

In Assassin's Creed II, the Renaissance assassin who becomes the game's protagonist is Ezio Auditore da Firenze.

Ezio is introduced as a young Florentine nobleman in 1476. After his family is caught in a political conspiracy and his father and brothers are executed, Ezio begins a long campaign against those responsible. His journey takes him through Florence, Monteriggioni, Venice, and other Italian locations.

The surname phrase “da Firenze” means “of Florence,” identifying his birthplace and family association. Ezio is not the same character as Altaïr, the protagonist of the first game, although the two are connected through the series' ancestral-memory premise. Ezio's story continues in Brotherhood and Revelations, making him one of the franchise's most extensively developed protagonists.
