Reconstruction
Between 762 and 764, the Tang state emerged from the An Lushan rebellion with its principal northern agricultural regions damaged, its transport networks unreliable, and its treasury under intense military pressure. The rebellion ended in 763, but peace did not immediately restore cultivation or distribution. Armies had repeatedly crossed Henan, Hebei, Hedong, and the approaches to Chang’an; Luoyang was plundered again in 762. In late 763, a Tibetan force briefly occupied Chang’an, demonstrating that the capital and its supply routes remained vulnerable.
The evidence describes overlapping regional shortages rather than one securely defined, empire-wide famine lasting precisely from 762 to 764. A particularly concrete report in Sima Guang’s later-compiled Zizhi Tongjian concerns Jiang-Huai in 762. Fiscal commissioner Yuan Zai ordered the collection of eight years of alleged tax arrears. Officials surrounded households possessing grain or textiles and confiscated half—and reportedly sometimes eight- or nine-tenths—of their property. People with reserves feared seizure, while others gathered in mountains and marshes beyond effective county control. In Jiangzhou, the same account records empty local stores, hungry inhabitants who could not bear further levies, and soldiers whose grain allowances were insufficient.
Sources do not provide a dependable menu for the hungry in these specific years. Ordinarily, northern households depended heavily on millet and increasingly on wheat foods, while rice was more important in Jiang-Huai and the lower Yangzi. When grain became scarce, households probably stretched available millet, wheat, or rice as thin gruel, but that is a reasonable reconstruction from staple use, not a directly recorded practice for this crisis. No securely attributable source identifies particular wild plants, animal substitutes, or famine recipes for 762–764.
The disruption was therefore not simply a harvest problem. Military requisitioning, abandoned fields, damaged canals, fragmented authority, forced taxation, and competition between civilians and armies all reduced access to food. Refugees, small cultivators, laborers, and households with little political protection were especially exposed. Nor should the dramatic fall between prewar and postwar census totals be treated as a literal death count: flight, lost records, and territories beyond central registration explain much of it.
The lasting significance lay in fiscal and logistical change. The court increasingly depended on the comparatively productive southeast and on officials who could move grain north by water. Reforms associated with Liu Yan rebuilt canal transport and linked salt revenues to state finance. Over subsequent decades, the rebellion’s aftermath helped shift the empire’s economic center toward the Yangzi regions and encouraged the replacement of the failing household-based tax order with the Two-Tax system of 780. The crisis thus exposed a durable truth of medieval food security: grain could exist, yet warfare, taxation, and broken distribution could still place it beyond the reach of hungry people.
Historical context
The eight-year An Lushan rebellion was ending after devastating much of the North China Plain. Chang’an and Luoyang had each changed hands, and a Tibetan army briefly occupied Chang’an in late 763. Tang registers counted about 48 million people before the rebellion but only about 17 million in 764; historians caution that this enormous decline mainly reflects displacement, administrative collapse, under-registration, and lost territory rather than a measured death toll. The Tang court survived with Uyghur military assistance while increasingly relying on rice, textiles, salt revenue, and tax remittances from the Yangzi basin and southeast.
Evidence
Written sources
StrongThe Zizhi Tongjian preserves specific accounts for 762 of aggressive collection of grain and textiles in Jiang-Huai, households fleeing or resisting officials, empty stores, local hunger, and inadequate military grain allowances. It was compiled in the eleventh century from earlier historical materials and is not an eyewitness record.
Dating
LimitedSevere food-system disruption is well supported during and after the rebellion, but 762–764 is a modern chronological bracket rather than a clearly documented, uniformly continuous famine of that exact duration.
Geographic attribution
LimitedDocumented distress affected multiple regions, including the northern war zone and Jiang-Huai. A single coordinate near Chang’an cannot represent the full geography, and some of the most detailed evidence for 762 concerns areas far southeast of the capital.
Food identification
LimitedSources directly mention grain or rice stores and allowances but do not identify a complete famine diet or specific substitutes for 762–764. Millet, wheat, and rice are regional staple reconstructions rather than observed crisis meals.
Preparation method
InterpretiveStretching grain as thin porridge is historically plausible, but no consulted source directly documents that preparation for this particular crisis.
Historical interpretation
ModerateModern scholarship strongly connects the rebellion with agricultural devastation, displacement, fiscal breakdown, military extraction, and a growing dependence on the southeastern economy. The relative contribution of harvest failure, warfare, taxation, and transport disruption varied by region.
Visual reconstruction
LimitedA reconstruction could defensibly show damaged fields, displaced households, guarded grain stores, tax collection, or interrupted transport, but specific clothing, foods, quantities, and individual actions would remain interpretive.

Limitations
- majortitle/date
Reliable evidence supports severe but geographically uneven wartime and postwar hunger; it does not clearly establish a single named, empire-wide famine continuously bounded by 762–764. The date range should be treated as an atlas reconstruction.
- moderatedescription.cause
War damage, military provisioning, transport failure, and coercive taxation are well supported. Locusts have not been securely verified as a material cause of a distinct 762–764 famine, and major chronologies of Tang locust outbreaks emphasize other years.
- moderatecoordinates
The coordinate represents Chang’an, but the strongest specific 762 evidence concerns Jiang-Huai and Jiangzhou, while broader war damage extended across Henan, Hebei, Hedong, and Guannei. A single North China point understates the event’s regional complexity.
- moderatedescription.mortality
Hunger and displacement are documented, but no reliable mortality total specifically for 762–764 was identified. The post-rebellion census collapse cannot be converted directly into famine deaths because registration failure, migration, and lost territorial control were substantial.
