Nonetheless the interior of the Empire remained largely untouched by warfare. The ''Pax Romana'' was an era of relative tranquility in which Rome endured neither major civil wars, such as the [[w:Crisis of the Third Century|perpetual bloodshed of the third century AD]], nor serious invasions, or killings, such as those of the [[w:Second Punic War|Second Punic War]] three centuries prior.
