TL;DR: A database of historical and archaeological information from 30 regions around the world over the last 10,000 years revealed that characteristics, such as social scale, economy, features of governance, and information systems, show strong evolutionary relationships with each other and that complexity of a society across different world regions can be meaningfully measured using a single principal component of variation.

TL;DR: It is found that the multidecadal precipitation and drought variations in the Central and Eastern Mediterranean cannot be explained by external forcings (solar variations, tropical volcanism); rather they were driven by internal climate dynamics.

TL;DR: The project "Complexities and networks in the Medieval Mediterranean and Near East" (COMMED) at the Division for Byzantine Research of the Institute for Medieval Research (IMAFO) as discussed by the authors focuses on the adaptation and development of concepts and tools of network theory and complexity sciences for the analysis of societies, polities and regions in the medieval world in a comparative perspective.

TL;DR: In this article, a recently proposed scenario of a climate-induced Collapse of the Eastern Mediterranean in the 11th century AD is discussed, and it demonstrates that such a scenario cannot be maintained when confronted with proxy data from various regions.

TL;DR: The Seshat: Global History Databank (Seshat) as discussed by the authors is a large-scale dataset of historical and archaeological data from the period from the Neolithic Revolution to the Industrial Revolution.
