Secular Cycles

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.

"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
