Cliodynamics /ˈkli.dˈnæmɪks/ is a transdisciplinary area of research integrating cultural evolution, economic history/cliometrics, macrosociology, the mathematical modeling of historical processes during the longue durée, and the construction and analysis of historical databases.[1] Cliodynamics treats history as science. Its practitioners develop theories that explain such dynamical processes as the rise and fall of empires, population booms and busts, spread and disappearance of religions. These theories are translated into mathematical models. Finally, model predictions are tested against data. Thus, building and analyzing massive databases of historical and archaeological information is one of the most important goals of cliodynamics.


The word cliodynamics is composed of clio- /ˈkli./ and -dynamics /dˈnæmɪks/. In Greek mythology, Clio is the muse of history. Dynamics, most broadly, is the study of how and why phenomena change with time.


The term was originally coined by Peter Turchin in 2003, and can be traced to the work of such figures as Ibn Khaldun, Jack Goldstone, Sergey Kapitsa, Randall Collins, Peter Turchin, John Komlos, Sergey Nefedov and Andrey Korotayev.

Mathematical modeling of historical dynamics[edit]

Many historical processes are dynamic (a dynamic process is one that changes with time). Populations increase and decline, economies expand and contract, states grow and collapse. A very common approach, which has proved its worth in innumerable applications (particularly, but not exclusively, in the natural sciences), consists of taking a holistic phenomenon and splitting it up into separate parts that are assumed to interact with each other. This is the dynamical systems approach, because the whole phenomenon is represented as a system consisting of several elements (or subsystems) that interact and change dynamically; that is, over time. In the dynamical systems approach, one sets out explicitly with mathematical formulae how different subsystems interact with each other. This mathematical description is the model of the system, and one can use a variety of methods to study the dynamics predicted by the model, as well as attempt to test the model by comparing its predictions with observed empirical, dynamic evidence. Cliodynamics is the application of this same approach to the social sciences in general and to the study of historical dynamics in particular.

Cliodynamics practitioners apply mathematical models to explain macrohistorical patterns – things like the rise of empires, social discontent, civil wars, and state collapse. Although the focus is usually on the dynamics of large conglomerates of people, the approach of cliodynamics doesn't preclude the inclusion of human agency in its explanatory theories. Such questions can be explored with agent-based computer simulations.

Isaac Asimov employed a fictional version of this discipline, called psychohistory, as a major plot device in his Foundation series of science fiction novels.

Databases and Data Sources[edit]

Cliodynamics relies on large bodies of evidence to test competing theories on a wide range of historical processes. This typically involves building massive stores of evidence. The rise of digital history and various research technologies have allowed huge databases to be constructed in recent years. Some prominent databases utilized by cliodynamics practitioners include the following:

As of 2012 the main achievements in Cliodynamics are:

Cliodynamics: The Journal of Quantitative History and Cultural Evolution[edit]

Cliodynamics: The Journal of Quantitative History and Cultural Evolution is a peer-reviewed web-based (open-access) journal that publishes both empirical and modeling articles. The first issue was published in December 2010.

Cliodynamics is a member of Scopus and the Directory of Open Access Journals (DOAJ)

University of Hertfordshire Cliodynamics Lab[edit]

The University of Hertfordshire's Cliodynamics Lab is the first lab in the world dedicated explicitly to the new research area of Cliodynamics. The Cliodynamics Lab is based at the University of Hertfordshire and is directed by Dr. Pieter François, who founded the Lab in 2015.
