Hasdrubal Gisco
Recent archaeological finds show that Lisbon grew around a pre-Roman settlement on the hill of the Castelo de São Jorge, as its ancient name, "Olissipo", indicates. During the Second Punic War, Mago, the younger brother of Hannibal, was stationed with his troops among the Cynetes, or Conii, in the Algarve, while Hasdrubal Gisco was encamped at the mouth of the Tagus on the Atlantic coast. After the defeat of Hannibal at the Battle of Zama in 202 BC, Rome decided to deprive Carthage of its most valuable possession, Hispania (the name given by the Romans to the whole of the Iberian Peninsula). With the decisive victory of Scipio at the Battle of Ilipa in Spain in 206 BC, the Carthaginian hold in Iberia was broken.
