In the 2007 video game Assassin's Creed, which Assassin is the playable protagonist?

Altaïr Ibn-La'Ahad is the playable protagonist of the 2007 video game Assassin's Creed.

Altaïr is a Syrian Assassin operating during the Third Crusade, chiefly in the cities of the Holy Land. At the beginning of the game, his arrogance causes him to violate key principles of the Assassin Brotherhood, and he is demoted by his mentor, Al Mualim. His missions to eliminate specific targets gradually become a path to restored rank and deeper understanding.

Players sometimes confuse Altaïr with Ezio Auditore, the hero of Assassin's Creed II and its sequels. Altaïr is the first major playable Assassin in the released series, while later games follow different historical characters connected through the Animus framework. The character also appears in later series lore, including Assassin's Creed: Revelations, which explores his life and legacy.

The name Altaïr is Arabic and is commonly associated with the star Altair, although the character's full name is Altaïr Ibn-La'Ahad. His signature weapon is the hidden blade, a defining tool of the Brotherhood.
