How to read the evidence badges

Primary text read: Civitas read the ancient or primary text for at least one figure on this card. Other figures may still be Wikipedia-compiled and are labelled.

Generic placeholder: crossed lines for a battle. Not an image of this event.

battle · May-September 751 CE

Battle of Talas (751 CE)

Frontier clash between Tang and Abbasid power in Central Asia; commonly linked to the westward transmission of papermaking (a claim that should be sourced separately before use).

Evidence: Primary text read Draft estimate

What the record says

Note Dates May-September 751; outcome: Abbasid victory.
Unverified (Wikipedia-compiled) Wikipedia-compiled (stub) casualties of the Tang side: Chinese sources 20,000-30,000 killed with ~2,000 surviving; Arab sources 45,000-50,000 killed and 20,000-25,000 captured. Modern strength estimates ~30,000 per side. Source discrepancy is the main finding.
Primary text PRIMARY-SOURCE figures: Zizhi Tongjian 216, Tianbao 10 (751) (read, zh.wikisource revid 1958791): Gao Xianzhi led 30,000 Fan and Han troops (蕃、漢三萬衆) some 700 li into the west, met the Dashi (Abbasid) army at Heluosi (Talas); after five days the Karluks defected and attacked with the Dashi; the Tang army was crushed, "the soldiers almost all dead, only a few thousand remaining". Eleventh-century compilation; claims, not measurements.

Confidence. low-medium (sources disagree 2x).

rebellion · 16 December 755-17 February 763

An Lushan Rebellion (755-763 CE)

Military governor revolt that cut Tang central fiscal control and empowered provincial military governors (jiedushi); canonical case for concept-rebellion and dynastic decline.

Evidence: Primary text read Draft estimate

What the record says

Unverified (Wikipedia-compiled) Dates 16 December 755 - 17 February 763; outcome: Tang survives (Wikipedia infobox "Tang victory").
Primary text PRIMARY-SOURCE registration figures (Ma Duanlin, Wenxian Tongkao juan 10, quoting Du You Tongdian; text read on zh.wikisource.org revid 1501681, 2026-10-11): households 9,619,254 in 754; 8,919,309 in 755 (persons 52,909,309 = 44,700,988 non-taxable + 8,208,321 taxable); 8,018,710 in 756; 1,933,134 in 760 (persons 16,990,386 = 14,619,587 + 2,370,799); 2,933,125 in 764. The source states a loss 755-760 of 5,982,584 households and 35,928,723 persons, which does not match simple subtraction of its own totals (6,986,175 households; 35,918,923 persons) - source-internal inconsistency, flagged.
Note These are REGISTERED counts, not deaths: Ma Duanlin himself comments that Tang registers are unreliable (concealment, flight, collapse of registration). Do NOT convert to mortality; any mortality estimate would need a demographic model (not done). See data-tang-registered-population-754-764.
Unverified (Wikipedia-compiled) Wikipedia lists casualties as heavy but uncertain; peak force sizes 600,000-700,000 vs 200,000-300,000 are loose (low confidence).

Confidence. medium (events); registered-population figures read in primary text; deaths NOT quantified.

conquest · October 763 CE (about 15 days)

Tibetan Occupation of Chang'an (763 CE)

Tibetan Empire exploits Tang weakness; the main Tibetan-era conflict record in this patch (Beckwith 1987 is the standard scholarly history).

Evidence: Primary text read Draft estimate

What the record says

Unverified (Wikipedia-compiled) Wikipedia (Tang-Tibet relations, stub): in October 763 Tibetan forces occupied Chang'an for about 15 days during the An Lushan aftermath, forcing the Tang emperor to flee to Shanzhou; claimed Tibetan force 200,000 (LOW confidence; likely inflated). Tibetan conquest of Tang Hexi/Longyou/Anxi territories followed the rebellion.
Candidate sources Candidate formal sources listed in the Wikipedia infobox/lead for this topic (METADATA-VERIFIED ONLY via Crossref/Open Library; NOT read; relevance to the figures above unverified): Norbu Dawa 2001, China's Tibet Policy.
Primary text PRIMARY-SOURCE (read 2026-10-12): Zizhi Tongjian 223 (Guangde 1, 763): in the 10th month the Tibetans, leading Tuyuhun, Dangxiang, Di and Qiang, "more than 200,000", crossed the Wei; Emperor Daizong fled to Shaanzhou; on the wuyin day the Tibetans entered Chang'an, set up Li Chenghong as emperor, and plundered the city, "Chang'an was emptied"; Guo Ziyi started with only 20 horsemen. Claims.
