“So why did strong, modern states not emerge in Latin America as they did in Europe? If there is a single factor that explains this outcome, it is the relative absence of interstate war in the New World. We have seen how central war and preparation for war were in the creation of modern states in China, Prussia, and France. Even in the United States, state building has been driven by national security concerns throughout the twentieth century. Though Europe has been remarkably peaceful since 1945, the prior centuries were characterized by high and endemic levels of interstate violence. Over the past two centuries, the major political acts that reconfigured the map of Europe—the French Revolution and Napoleonic Wars, and the wars of unification of Italy and Germany—all involved high levels of violence, culminating in the two world wars of the twentieth century. There has been plenty of violence in Latin America, of course: today the region is infested with drug cartels, street gangs, and a few remaining guerrilla groups, all of which inflict enormous sufferings on local populations. But in comparison with Europe, Latin America has been a peaceful place in terms of interstate war. This has been a blessing for the region, but it has also left a problematic institutional legacy.”
