Can mathematical models predict the collapse of empires and the rise of social unrest?
In short: Peter Turchin, a specialist in cliodynamics, uses mathematical modeling to analyze historical societies. By tracking social indicators, he identifies patterns in how empires evolve and collapse. His research suggests that elite overproduction and inequality are key drivers of political instability, potentially signaling turbulent times for modern nations today.
Peter Turchin is a Russian-American scientist who pioneered cliodynamics, a discipline that applies mathematical and statistical analysis to historical macrosociology. Born in 1957, Turchin originally trained as a theoretical biologist before pivoting to the study of historical dynamics. He currently holds positions at the Complexity Science Hub Vienna and the University of Oxford, and he serves as a director for the Seshat: Global History Databank. His work seeks to uncover general principles governing the rise and fall of complex societies.
Central to Turchin's research is the concept of elite overproduction, which occurs when a society produces more potential elite members than its power structure can accommodate. This surplus of ambitious individuals, who feel aggrieved by their limited status, often drives social instability. Turchin has collaborated with Jack Goldstone to analyze how self-interested elites, by resisting taxation and restricting upward mobility, exacerbate inequality and fuel political turbulence. He argues that historical stability often depends on whether a ruling class is willing to mitigate economic disparities to forestall crisis.
Turchin also investigates the relationship between population pressure and internal warfare. By examining historical data from regions such as the Roman Empire and various Chinese dynasties, he and his collaborators have observed that population numbers and warfare intensity often oscillate in a predictable, phase-shifted pattern. In 2010, Turchin utilized social indicators to forecast growing unrest in the United States and Western Europe for the 2020s. He views these cycles as a buildup of deadwood in a forest, where a single spark can trigger a massive social conflagration if underlying structural issues remain unaddressed.
While his methods are rigorous, Turchin's work remains a subject of intense academic scrutiny. His research spans over 200 scientific articles and several books, including 'Ages of Discord' and 'End Times'. By reinterpreting historical concepts like Ibn Khaldun's 'asabiyya'—or collective solidarity—Turchin aims to provide a scientific framework for understanding the long-term evolution of human civilization, emphasizing that the path toward political disintegration is often paved by the choices of those in power.
