It was heavily implied in the Romulus Scrolls that the dagger was the same weapon Brutus used to kill Gaius Julius Caesar. The weapon was unlocked and made usable by collecting all the Keys of Romulus from the different Lairs of Romulus, and was found in the same underground chamber as the Armor of Brutus. It was the best short blade weapon available to the AssassinEzio Auditore during the 16th century.

Trivia
The Dagger of Brutus is modeled after a Roman Pugio, a type of dagger used as a secondary weapon by File:Dagger of Brutus sketch.jpgDagger of Brutus sketch.Roman soldiers during the 1st Century AD.
When Ezio wields the Dagger of Brutus, enemy morale is reduced by 20 points – low rank guards and crossbowmen will run away after the death of only one regular guard.
The dagger's kill animations are unique, and differ from those of other short blade weapons that Ezio can wield.
