In War and Peace and War, Peter Turchin uses his expertise in evolutionary biology to offer a bold new theory about the course of world history. Turchin argues that the key to the formation of an empire is a society's capacity for collective action. He demonstrates that high levels of cooperation are found where people have to band together to fight off a common enemy, and that this kind of cooperation led to the formation of the Roman and Russian empires, and the United States. But as empires grow, the rich get richer and the poor get poorer, conflict replaces cooperation, and dissolution inevitably follows. Eloquently argued and rich with historical examples, War and Peace and War offers a bold new theory about the course of world history with implications for nations today.

WE ARE ON THE WRONG TRACK Seventy percent of Americans (and counting) think so. The real wage of a US worker today is less than it was 40 years ago-but there are four times as many multimillionaires. As inequality grows, the politics become more poisonous. Every year, more and more Americans go on shooting sprees, killing strangers and passers-by-and now, increasingly, representatives of the state. Troubling trends of this kind are endlessly discussed by public intellectuals and social scientists. But mostly, they talk about only a small slice of the overall problem. After all, how on earth can yet another murderous rampage have anything to do with polarization in Congress? And is there really a connection between too many multimillionaires and government gridlock? Historical analysis shows that long spells of equitable prosperity and internal peace are succeeded by protracted periods of inequity, increasing misery, and political instability. These crisis periods-"Ages of Discord"-have recurred in societies throughout history. Modern Americans may be disconcerted to learn that the US right now has much in common with the Antebellum 1850s and, more surprisingly, with ancien régime France on the eve of the French Revolution. Can it really be true that there is nothing new about our troubled time, and that similar ages arise periodically for similar underlying reasons? Ages of Discord marshals Structural-Demograpic Theory and detailed historical data to show that this is, indeed, the case. The book takes the reader on a roller-coaster ride through American history, from the Era of Good Feelings of the 1820s to our first Age of Discord, which culminated in the American Civil War, to post-WW2 prosperity and, finally, to our present, second Age of Discord.

Taking up the problem of territorial dynamics - why some polities at certain times expand and at other times contract - this book shows that a similar research program can advance our understanding of dynamical processes in history. It investigates the dynamics predicted by the models, and contrasts model predictions with empirical patterns.

Why do organisms become extremely abundant one year and then seem to disappear a few years later? Why do population outbreaks in particular species happen more or less regularly in certain locations, but only irregularly (or never at all) in other locations? Complex population dynamics have fascinated biologists for decades. By bringing together mathematical models, statistical analyses, and field experiments, this book offers a comprehensive new synthesis of the theory of population oscillations. Peter Turchin first reviews the conceptual tools that ecologists use to investigate population oscillations, introducing population modeling and the statistical analysis of time series data. He then provides an in-depth discussion of several case studies--including the larch budmoth, southern pine beetle, red grouse, voles and lemmings, snowshoe hare, and ungulates--to develop a new analysis of the mechanisms that drive population oscillations in nature. Through such work, the author argues, ecologists can develop general laws of population dynamics that will help turn ecology into a truly quantitative and predictive science. Complex Population Dynamics integrates theoretical and empirical studies into a major new synthesis of current knowledge about population dynamics. It is also a pioneering work that sets the course for ecology's future as a predictive science.

Many historical processes exhibit recurrent patterns of change. Century-long periods of population expansion come before long periods of stagnation and decline; the dynamics of prices mirror population oscillations; and states go through strong expansionist phases followed by periods of state failure, endemic sociopolitical instability, and territorial loss. Peter Turchin and Sergey Nefedov explore the dynamics and causal connections between such demographic, economic, and political variables in agrarian societies and offer detailed explanations for these long-term oscillations--what the authors call secular cycles. Secular Cycles elaborates and expands upon the demographic-structural theory first advanced by Jack Goldstone, which provides an explanation of long-term oscillations. This book tests that theory's specific and quantitative predictions by tracing the dynamics of population numbers, prices and real wages, elite numbers and incomes, state finances, and sociopolitical instability. Turchin and Nefedov study societies in England, France, and Russia during the medieval and early modern periods, and look back at the Roman Republic and Empire. Incorporating theoretical and quantitative history, the authors examine a specific model of historical change and, more generally, investigate the utility of the dynamical systems approach in historical applications. An indispensable and groundbreaking resource for a wide variety of social scientists, Secular Cycles will interest practitioners of economic history, historical sociology, complexity studies, and demography.
