The pugio (; plural: pugiones) was a dagger used by Roman soldiers as a sidearm. It seems likely that the pugio was intended as an auxiliary weapon, but its exact purpose for the soldier remains unknown though it seems it could have been used for close quarters fighting. Officials of the empire took to wearing ornate daggers in the performance of their offices, and some would wear concealed daggers for defense in contingencies.
