The Better Angels of Our Nature: Why Violence Has Declined: Summary & Key Insights

To understand how far we’ve come, we must start where humanity began — in small, stateless societies where governance was absent and personal retaliation ruled all. Archaeological data and ethnographic studies paint this grim picture vividly: in prehistoric hunter-gatherer bands, a significant portion of males died due to violent encounters. Life was indeed, as Hobbes wrote, 'nasty, brutish, and short.'

The formation of agrarian settlements and the rise of states changed everything. When centralized authority emerged, it began to monopolize the legitimate use of force. Kings, chiefs, and later legal institutions assumed what individuals once claimed — the right to inflict punishment. It may sound paradoxical, but the development of government, even one prone to tyranny, was a step toward peace. By curbing cycles of vendetta and retaliation, states reduced interpersonal violence. Death by combat gave way, progressively, to judgment by courts.

The pacification process reminds us that order itself — even coercive order — is not antithetical to liberty. It is the primordial foundation upon which peace is built. When a community’s sense of justice migrates from personal revenge to collective legal systems, an enormous transformation occurs: the norm of violence loses legitimacy. You see this in the declining archaeological traces of violent death across millennia. The emergence of rule-governed societies marks humanity’s first great leap toward civility.

The next great transformation unfolded within established societies, most strikingly in medieval and early modern Europe. Records of homicide, duels, and torture in these eras reveal the pervasive brutality of everyday life. But then, gradually, cultural refinement and social norms began reshaping behavior. The influences here were manifold: the growth of commerce, the rise of urbanization, and the spread of manners and self-control through education and etiquette.

I draw extensively on the work of historian Norbert Elias, who showed how social mores evolved to favor restraint. As populations grew denser, people had to coordinate their conduct to coexist. Violent reactivity became less tolerable. Economic interdependence meant that harming others was economically self-defeating. Trade replaced pillage; contracts replaced coercion.

Language and literature also played subtle but powerful roles. Conduct manuals taught not only etiquette but empathy — how to consider the feelings of others. The concept of honor morphed from physical dominance to moral reputation. As interpersonal styles softened, the underlying psychology of aggression weakened. This civilizing process, though uneven and imperfect, laid the groundwork for modern sensitivity to cruelty and injustice.
