Secular Cycles

Unraveling the dynamics of History through Demographic, Economic, and Political Shifts in Agrarian Societies

Aug 9, 2009Princeton University Press

About the Book

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, and provides an explanation of long-term oscillations in demographic, social, and political structures of complex societies. 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.

Review Highlights

"This book is an audacious and ambitious attempt to promote the viewpoint that historical progression runs according to certain regular patterns. . . . I am fascinated by this book, particularly by the theoretical framework which is laid out in the introductory and concluding chapters. . . . [T]he main strength of the book lies in its scope, reminiscent of the broad perspectives of classical economists. It is the type of scholarship which proves that historical narrative can be fascinating." --- Harry Kitsikopoulos, EH.net "Those who are interested in grand social theories will want to read and reflect. I suspect that there will be many who then will rebut." --- Brian J. L. Berry, American Journal of Sociology "Turchin and Nefedov have set a very ambitious task for themselves. . . . [T]hey should be applauded for producing a work of very broad historical sweep and reminding us that developing general laws--or more plausibly, general tendencies--of historical dynamics remains a tantalizing proposition." --- David S. Jacks, Australian Economic History Review "[T]he standard of historical scholarship is excellent and opens the floor to interesting challenges for further empirical explorations." --- Laura Panza, Economic Record " Secular Cycles is an ambitious, audacious, and engaging achievement from two very talented scholars. This stimulating book will attract interdisciplinary attention from those interested in global history and secular economic change." ― Cormac Ó Gráda, author of Famine "I am impressed and delighted by the breadth, rigor, creativity, originality, and power of this book. The graphs present the data in a fashion that will be clear to any audience, and the text is straightforward and persuasive. This book carries the study of historical dynamics to a whole new level." ― Jack A. Goldstone, George Mason University

Political instability may be a contributor in the coming decade

Feb 3, 2010Turchin, P.

The next decade is likely to be a period of growing instability in the United States and western Europe, which could undermine the sort of scientific progress you describe in the Opinion collection of '2020 visions' (Nature 463, 26–32; 2010). Quantitative historical analysis reveals that complex human societies are affected by recurrent — and predictable — waves of political instability (P. Turchin and S. A. Nefedov Secular Cycles Princeton Univ. Press; 2009). In the United States, we have stagnating or declining real wages, a growing gap between rich and poor, overproduction of young graduates with advanced degrees, and exploding public debt. These seemingly disparate social indicators are actually related to each other dynamically. They all experienced turning points during the 1970s. Historically, such developments have served as leading indicators of looming political instability.

A Primer on Statistical Analysis of Dynamical Systems in Historical Social Sciences (with a Particular Emphasis on Secular Cycles)

Jan 2, 2005Turchin, P.

This primer explicates the conceptual foundations of the statistical approach to detecting dynamical feedbacks. It is assumed that we have time-series data on several aspects of the studied system. The basic idea of the approach is to regress discrete rates of change of measured variables on variables themselves. I discuss several issues involved in the analysis, such as how to select the appropriate time step, or the delay parameter. The goal of the analysis is to determine whether a particular predictor variable, or set of variables, has a statistically detectable effect on the response. This is accomplished by cross-validation.
