Ancient Inner Asian Nomads: Their Economic Basis and Its Significance in Chinese History

Such non-chinese people as the rong, di, and hu are often portrayed in the traditional historiography of ancient China as greedy, aggressive, and acquisitive (Sinor 1978; Honey 1990). Chinese writings of the Zhou dynasty (c. 1050–256 b.c. ) contain many instances of unflattering statements aimed at foreign peoples: the Zuo zhuan compares the Rong and Di to wolves (ZZ, 1:209); the Zhan guo ce says the state of Qin shares the same attributes as the Rong and Di—the heart of a tiger or wolf, greed, and cruelty (ZGC, 11:869; cf. Crump 1970:436). Foreign peoples were often considered “have-nots” with an insatiable lust for Chinese goods, mainly silk, grains, and, later, tea. This stereotype, which developed in the historical sources along with the process of crystallization of the Chinese ethnocultural identity and codification of the written and oral traditions, was regarded as sufficient to account for otherwise complex social and political phenomena. In the course of time, with the historical development of powerful nomadic states confronting China militarily and politically, the attributes of “greedy” and “ravenous” stuck essentially to those people who “moved in search of grass and water”: the pastoral nomads.

Pluvials, droughts, the Mongol Empire, and modern Mongolia

Significance A 1,112-y tree-ring record of moisture shows that in opposition to conventional wisdom, the climate during the rise of the 13th-century Mongol Empire was a period of persistent moisture, unprecedented in the last 1,000 y. This 15-y episode of persistent moisture likely led to a period of high grassland productivity, contributing fuel to the Mongol Empire. We also present evidence that anthropogenic warming exacerbated the 21st-century drought in central Mongolia. These results indicate that ecosystems and societies in semiarid regions can be significantly affected by unusual climatic events at the decadal time scale. Although many studies have associated the demise of complex societies with deteriorating climate, few have investigated the connection between an ameliorating environment, surplus resources, energy, and the rise of empires. The 13th-century Mongol Empire was the largest contiguous land empire in world history. Although drought has been proposed as one factor that spurred these conquests, no high-resolution moisture data are available during the rapid development of the Mongol Empire. Here we present a 1,112-y tree-ring reconstruction of warm-season water balance derived from Siberian pine (Pinus sibirica) trees in central Mongolia. Our reconstruction accounts for 56% of the variability in the regional water balance and is significantly correlated with steppe productivity across central Mongolia. In combination with a gridded temperature reconstruction, our results indicate that the regional climate during the conquests of Chinggis Khan’s (Genghis Khan’s) 13th-century Mongol Empire was warm and persistently wet. This period, characterized by 15 consecutive years of above-average moisture in central Mongolia and coinciding with the rise of Chinggis Khan, is unprecedented over the last 1,112 y. We propose that these climate conditions promoted high grassland productivity and favored the formation of Mongol political and military power. Tree-ring and meteorological data also suggest that the early 21st-century drought in central Mongolia was the hottest drought in the last 1,112 y, consistent with projections of warming over Inner Asia. Future warming may overwhelm increases in precipitation leading to similar heat droughts, with potentially severe consequences for modern Mongolia.

The Northern Frontier in Pre–Imperial China

The northern frontier of China has long been recognized as something more than a simple line separating natural zones, political entities, or ethnic groups. This frontier has been represented as the birthplace of independent cultures and the habitat of peoples whose lifestyle, economic activities, social customs, and religious beliefs became, from the Bronze Age onward, gradually but increasingly distant from the civilization of the Central Plain. This distinct cultural region, often called the “Northern Zone” of China, comprises the interlocking desert, steppe, and forest regions from Heilong jiang and Jilin in the east to Xinjiang in the west. The frontier between China and the north has also been envisaged as a bundle of routes and avenues of communications through which peoples, ideas, goods, and faiths flowed incessantly between West and East. In economic terms, it provided the Chinese with a source of foreign goods as well as a market for domestic production. The process by which the northern frontier acquired these qualifications was a long one. While its complexities cannot be captured in a single image, the Great Wall – this symbolic and material line that came into existence as a unified system of fortifications with the establishment of the Qin empire in 221 B.C. – can be seen as the culmination of a long process of cultural differentiation that embraces several aspects.

Climatic and environmental aspects of the Mongol withdrawal from Hungary in 1242 CE

The Mongol invasion of Eastern Europe, and especially its sudden withdrawal from Hungary in 1242 CE, has generated much speculation and an array of controversial theories. None of them, however, considered multifaceted environmental drivers and the coupled analysis of historical reports and natural archives. Here we investigate annually resolved, absolutely dated and spatially explicit paleoclimatic evidence between 1230 and 1250 CE. Documentary sources and tree-ring chronologies reveal warm and dry summers from 1238–1241, followed by cold and wet conditions in early-1242. Marshy terrain across the Hungarian plain most likely reduced pastureland and decreased mobility, as well as the military effectiveness of the Mongol cavalry, while despoliation and depopulation ostensibly contributed to widespread famine. These circumstances arguably contributed to the determination of the Mongols to abandon Hungary and return to Russia. While overcoming deterministic and reductionist arguments, our ‘environmental hypothesis’ demonstrates the importance of minor climatic fluctuations on major historical events.

Warfare in Inner Asian History (500-1800)

Military developments in Inner Asia lay at the basis of the rise of a number of Ancient and Early Modern Empires. This is the first scholarly work to embrace Inner Asian military history across a broad spatial and chronological spectrum, from the Turks and Uighurs to the Pechenegs, and from the Mongol invasion of Syria to the Manchu conquest of China. Based on previously unknown and until now underestimated sources, the contributors to this volume explore the context, development, and characteristic features of Inner Asian warfare, making original contributions to our understanding of Asian and world history.

The Eldgjá eruption: timing, long-range impacts and influence on the Christianisation of Iceland

The Eldgjá lava flood is considered Iceland’s largest volcanic eruption of the Common Era. While it is well established that it occurred after the Settlement of Iceland (circa 874 CE), the date of this great event has remained uncertain. This has hampered investigation of the eruption’s impacts, if any, on climate and society. Here, we use high-temporal resolution glaciochemical records from Greenland to show that the eruption began in spring 939 CE and continued, at least episodically, until at least autumn 940 CE. Contemporary chronicles identify the spread of a remarkable haze in 939 CE, and tree ring-based reconstructions reveal pronounced northern hemisphere summer cooling in 940 CE, consistent with the eruption’s high yield of sulphur to the atmosphere. Consecutive severe winters and privations may also be associated with climatic effects of the volcanic aerosol veil. Iceland’s formal conversion to Christianity dates to 999/1000 CE, within two generations or so of the Eldgjá eruption. The end of the pagan pantheon is foretold in Iceland’s renowned medieval poem, Vǫluspá (‘the prophecy of the seeress’). Several lines of the poem describe dramatic eruptive activity and attendant meteorological effects in an allusion to the fiery terminus of the pagan gods. We suggest that they draw on first-hand experiences of the Eldgjá eruption and that this retrospection of harrowing volcanic events in the poem was intentional, with the purpose of stimulating Iceland’s Christianisation over the latter half of the tenth century.

Environmental Stress and Steppe Nomads: Rethinking the History of the Uyghur Empire (744–840) with Paleoclimate Data

Newly available paleoclimate data and a re-evaluation of the historical and archaeological evidence regarding the Uyghur Empire (744–840)—one of several nomadic empires to emerge on the Inner Asian steppe—suggests that the assumption of a direct causal link between drought and the stability of nomadic societies is not always justified. The fact that a severe drought lasting nearly seven decades did not cause the Uyghur Empire to collapse, to wage war, or to disintegrate gives rise to speculations about which of its characteristics enabled it to withstand unfavorable climatic conditions and environmental change. More broadly, it raises questions about the complex suite of strategies and responses that may have been available to steppe societies in the face of environmental stress.
