Intensive pastoralism facilitated the rise of the Tang Dynasty in China
摘要
Climate change has long been regarded as an important driver of societal changes, largely because of its significance for agricultural production. However, our understanding of how the development of pastoralism affected societal changes during the historical period has been constrained by the paucity of historical documents and reliable and continuous records of grazing activity. Here, we utilize high-resolution records of coprophilous fungal spores from Tian’E Lake and Gonghai Lake in northern China, to reconstruct changes in grazing intensity during the Tang Dynasty. We compared our results with palaeoclimate reconstructions and documentary evidence of societal changes, to evaluate linkages among the natural environment, subsistence strategies, and the rise and fall of the Tang Dynasty. Based on structural equation modelling, we hypothesize that intensive pastoralism under a warm and wet climate facilitated the rise of the Tang Dynasty. We also infer that horse rearing played a crucial role in promoting the stability and rise of society in China during this period. This study contributes to an understanding of the relationships between pastoralism and the level of socioeconomic development, as well as military strength, during the pre-industrial period.
