The work traces Rome's rise from unifying Italy through its struggles with Carthage and the Greek world, recounting the contest over Sicily, the emergence of Carthaginian leaders and the campaigns of Hannibal including major battles, and the eventual Roman victories that ended Punic and Hellenistic resistance. It then surveys Roman expansion in the west and interventions in eastern Mediterranean wars, followed by discussions of Roman governance, land and monetary systems, religious customs, and developments in literature and art.
