After defeating Carthage the Romans went on to become the Mediterranean's dominant power, successfully campaigning in Greece, (Aemilius Paulus decisive victory over Macedonia at the Battle of Pydna), in the Middle East (Lucius Licinius Lucullus, Gnaeus Pompeius Magnus), in Gaul (Gaius Julius Caesar) and defeating several Germanic tribes (Gaius Marius, Germanicus). While Roman armies suffered several major losses, their large population and ability (and will) to replace battlefield casualties, their training, organization, tactical and technical superiority enabled Rome to stay a predominant military force for several centuries, utilizing well trained and maneuverable armies to routinely overcome the much larger "tribal" armies of their foes (see Battles of Aquae Sextiae, Vercellae, Tigranocerta, Alesia).
