There are traces of violence and warfare from the earliest periods of human history, and by the Classical era wars were common events and, along with politics, became the major concern of historians. Greeks defeated Persian invasions, then fought each other. Alexander swept through the Persian empire. Rome and Carthage waged war on an immense scale, and at the end of it the Carthaginian Republic was eradicated. Rome created and maintained through military force an empire embracing much of the known world.
Wars were important and shaped the development of the ancient world, but how should we understand them? Battles were major events, sometimes deciding wars, and were clearly important and need to be understood. Yet there was a lot more to ancient warfare than pitched battles, and it is vital to look at the attack and defence of fortified settlements and strongholds, and at lower level raids and skirmishes. The story of warfare in the Greek and Roman worlds is not simple, but remains of fundamental importance for understanding the era.
