Abstract: Do human societies from around the world exhibit similarities in the way that they are structured, and show commonalities in the ways that they have evolved? These are long-standing questions that have proven difficult to answer. To test between competing hypotheses, we constructed a massive repository of historical and archaeological information known as " Seshat: Global History Databank. " We systematically coded data on 414 societies from 30 regions around the world spanning the last 10,000 years. We were able to capture information on 51 variables reflecting nine characteristics of human societies, such as social scale, economy, features of gover-nance, and information systems. Our analyses revealed that these different characteristics show strong relationships with each other and that a single principal component captures around three-quarters of the observed variation. Furthermore, we found that different characteristics of social complexity are highly predictable across different world regions. These results suggest that key aspects of social organization are functionally related and do indeed coevolve in predictable ways. Our findings highlight the power of the sciences and humanities working together to rigorously test hypotheses about general rules that may have shaped human history. cultural evolution | sociopolitical complexity | comparative history | comparative archaeology | quantitative history

Instead, it points to cross-cultural parallels in the co-evolution of egalitarian ideals and constraints on political authority with sociopolitical complexity. The first book-length publication to make use of Seshat’s systematic approach to collecting information about the human past, The Seshat History of the Axial Age expands the Axial Age debate beyond first-millennium BCE Eurasia. Fourteen chapters survey earlier and later periods as well as developments in regions previously neglected in Axial Age discussions. The conclusion? There was no identifiable Axial Age confined to a few Eurasian hotspots in the last millennium BCE. However, “axiality” as a cluster of traits emerged time and again whenever societies reached a certain threshold of scale and level of complexity. Co-editors Daniel Hoyer and Jenny Reddish paired some of the world’s leading historians, archaeologists, and anthropologists with members of the Seshat team. Hoyer, Project Manager with Seshat, is a historian and social scientist specializing in cross-cultural historical analysis. Reddish, Seshat’s Lead Editor, is an anthropologist working on the material correlates of cultural systems from societies around the world. She is based at the Complexity Science Hub, Vienna. Seshat: Global History Databank was founded in 2011 to bring together the most current and comprehensive knowledge about human history in one place, collecting what is known about the social and political organization of human societies to track how civilizations have evolved over time. Seshat History of the Axial Age is the first entry in the Seshat Histories series.
