The gens Hostilia was an ancient family at Rome, which traced its origin to the time of Romulus. The most famous member of the gens was Tullus Hostilius, the third King of Rome; however, all of the Hostilii known from the time of the Republic were plebeians. Several of the Hostilii were distinguished during the Punic Wars. The first of the family to obtain the consulship was Aulus Hostilius Mancinus in 170 BC.[1]
