Olisipo

Municipium Cives Romanorum Felicitas Julia Olisipo (in Latin: Olisippo or Ulyssippo ; in Greek: Ολισσιπο, Olissipo, or Ολισσιπόνα, Olissipóna) was the ancient name of modern day Lisbon while part of the Roman Empire.

During the Punic wars, after the defeat of Hannibal the Romans decided to deprive Carthage of its most valuable possession, Hispania. After the defeat of the Carthaginians by Scipio Africanus in eastern Hispania, the pacification of western Hispania was led by Consul Decimus Junius Brutus Callaicus. He obtained the alliance of Olisipo (which sent men to fight alongside the Roman legions against the northwestern Celtic tribes) by integrating it into the Empire in 138 BC.
