Chapter 12 Research Reconnaissance
Scholarly-foundation audit of the three Chapter 12 decks and their background essays, with sources, a primary-source shortlist, and the source-verified deck revisions
Audit disposition. This reconnaissance covers the three current FA26 decks for Chapter 12 (Mongol Conquest and State-Building, Yuan Hierarchy and Global Exchange and Displaced Elites and the Collapse of Yuan Rule), the revised Lecture 1 background essay and two new essays for Lectures 2 and 3. The three-lecture roadmap passes. The decks are accurate, well sourced and already careful where Ebrey is weakest: they had absorbed an earlier outside audit, and none carried a visible "outside the textbook" tag. The check found one small overclaim on a visible slide (Lec1 V, where the Phags-pa script was ordered "for his whole empire"; the decree of 1269 was for official documents), which has been softened. Otherwise it found textbook slips that students will meet in the reading: Khubilai's reign misprinted as "1360–1394," "only plundered," Dadu "in 1264," the Mongol killer who "merely had to pay a fine," the "new style" of blue-and-white, the "2 percent" of posts and the spelling "Ni Can." The rule for this revision was that the decks contradict Ebrey only where a reliable source (the Cambridge History of China, the Yuan shi, a scholarly monograph or a peer-reviewed article) confirms the correction. Each confirmed item now has an instructor note giving the textbook's version and a "Source beyond Ebrey" line, and each deck's Sources slide lists those works under "Further reading beyond Ebrey." Items that could not be confirmed (Renzong as the "first" Mongol emperor to read Chinese, Guan Hanqing's play count) were left as the decks already had them, softened in the notes. Section 8 gives every item checked, with its verdict, source and action.
1. Governing standards and scope
Research precedes presentation. Ebrey's Chapter 12, "China Under Mongol Rule (1215–1368)," pp. 198–210 in the course PDF, is the course baseline, not its ceiling. Dates, names, numbers and quotations in the decks were checked against the textbook (from an OCR of the course PDF, with the page images consulted where the OCR was doubtful), against the Cambridge History of China, volumes 6 and 7, and against the Chinese text of the Yuan shi for every passage the decks translate. Where Ebrey's statements conflict with confirmed scholarship, the essays follow the scholarship and flag the textbook.
The rule for fixes is the course rule. Visible slides teach the correct history. The textbook's discrepancy is explained only in an instructor note, with a brief "Source beyond Ebrey" line, and the outside work is listed on the Sources slide. No slide carries a visible "outside the textbook" tag. Slide letters are permanent, and no slide is added, removed or relettered.
Audience: the instructor's preparation and advanced students. Chapter 12 is taught as independent study, so the decks are Study Buddy editions that students read on their own. The essays keep plain language and define terms, but cite real scholarship in footnotes and end with annotated reading lists.
2. Textbook baseline
Ebrey's chapter supplies the spine: Chinggis, Xia and Jin (pp. 198–199); Ögödei, Yelü Chucai and the tax farmers (p. 199); Möngke, Khubilai, Dadu, the Yuan name and the province (pp. 200–201); the conquest of the Southern Song (pp. 201–202); the Documents feature on the Luoluo (pp. 202–203); life under the Mongols, the occupational categories and the four grades (pp. 202–205); the Biography of Hao Jing (p. 204); the Material Culture feature on blue-and-white porcelain and the legal restrictions (p. 205); the economy and the decline after 1294 (pp. 205–206); the educated elite, Zhao Mengfu and the painters (pp. 206–208); drama (pp. 208–209); the summary (p. 209); and Making Comparisons, "Food Cultures" (p. 210). The reading guide sets eleven review questions, all covered by the decks.
The chapter is clear and well proportioned, with one structural gap: the fall of the Yuan gets a few sentences (p. 206), and the Red Turbans, the Yellow River and Zhu Yuanzhang do not appear until Chapter 14. Lecture 3 fills that gap from the Cambridge History. Statements needing correction or caution:
- Khubilai "r. 1360–1394" (p. 198): a misprint for 1260–1294 (CHC 6, p. 414).
- "Mongol armies did not try to control territory; they only plundered it" (p. 199): overseers from 1214–1215 and Muqali's command from 1217 (CHC 6, pp. 357–358, 373).
- "In 1264, Khubilai constructed a new capital" (p. 200): ordered 1266, begun 1267 (CHC 6, pp. 454, 458).
- Catapult stones "up to a hundred pounds" (p. 201): the Yuan shi gives 150 jin, about 90 kg (ch. 203).
- A Mongol "merely had to pay a fine" for murdering a Chinese (p. 205): campaign service and the full burial money (Yuan shi, ch. 105).
- Jingdezhen artists "invented a new style of decoration" (pp. 205–206): correct for the Yuan underglaze style, but Tang blue-and-white is earlier (Krahl, 2010).
- Renzong "the first Mongol emperor able to both read and speak Chinese" (p. 206): not confirmed either way.
- Exams reestablished "in 1313" and "in 1315" (p. 206): both correct, for the edict and the first metropolitan examination.
- "Only about 2 percent of the positions" filled through the examinations (p. 206): Hsiao gives slightly more than 4 percent of ranked civil officials (CHC 6, p. 517).
- "Ni Can" (p. 208): Ni Zan.
- Guan Hanqing, "sixty plays, fifteen of which survive complete" (p. 208): counts differ among reference works.
3. Inventory and authority determination
Authoritative for this audit: the three current FA26 decks in reveal_decks/chapter-12/, the Chapter 12 reading guide and the chapter README.
- Lecture 1,
HIST270_ch12_lec1_mongol_conquest_state_building_revised_FA26.html: 36 slides, A–AJ, with uppercase permanent letters; Review Questions 1–4, with a Pierian Spring (AE–AI). It supersedes the earlier 28-slide…_revFA26.html(a–bb) that the README still lists; an untracked copy of that file sits inarchive/, and the README table should be updated. - Lecture 2,
HIST270_ch12_lec2_yuan_hierarchy_global_exchange_revFA26.html: 24 slides, a–x; Review Questions 5 and 8. - Lecture 3,
HIST270_ch12_lec3_displaced_elites_yuan_collapse_revFA26.html: 26 slides, a–z; Review Questions 6, 7, 9, 10 and 11. - Archived, not audited: the three
_revSU26decks and the old whole-chapterHIST270_ch12_studybuddy.html.
One background essay existed, for Lecture 1. It was accurate but short and had no footnotes, approximate page anchors and one overstatement ("at first they did not try to hold territory"). It has been revised. The README's open items (unchecked quotations and dates from memory) were all checked in this pass and confirmed; see Section 8.
4. Fresh chapter-wide research reconnaissance
The scholarship on Mongol China has moved in four directions since the textbook's framework was set, and each affects the decks.
The Mongols as empire builders. Thomas Allsen's work (Mongol Imperialism, 1987; Culture and Conquest in Mongol Eurasia, 2001) and the Cambridge History volume 6 (1994) replaced the picture of raiders who learned to govern late with one of an empire that counted, taxed and moved people from early on. Ruth Dunnell and Timothy May have refined the military history, and Igor de Rachewiltz's Secret History (2004) is the standard source edition. Lecture 1's "not just plunder" slide (F) reflects this work.
The four classes. Meng Siming's 1938 model of a rigid ethnic hierarchy, still behind Ebrey's "four grades," has been qualified by Funada Yoshiyuki, Elizabeth Endicott-West and Mote: the labels were real in particular rules but were applied unevenly, and semu was a Chinese administrative category. Lecture 2's slide g gives students this debate.
Eurasian exchange. Allsen, Morris Rossabi (Voyager from Xanadu, 1992), Michal Biran and others have made the Mongol period a central case in world history. For porcelain, the Belitung wreck (published 2010) changed the story of origins, and Robert Finlay's The Pilgrim Art (2010) set blue-and-white in a global frame.
Scholars, art and the fall. Mote's essay on eremitism, Jennifer Jay on loyalism and Benjamin Elman on the examinations support Lecture 3's first two blocks; Stephen West and Wilt Idema have changed how Yuan drama is read, by showing how much the Ming editors altered the texts; James Cahill and Shane McCausland remain the base for painting. On the fall, John Dardess's Conquerors and Confucians (1973) and his Cambridge History chapter, with Mote's chapter in volume 7, supply the narrative Ebrey omits, and Timothy Brook's The Troubled Empire (2010) adds climate and disease.
5. Three-lecture roadmap audit
The roadmap passes. Each lecture carries one story arc: two stages of conquest (Lec1, RQ1–4); walls between people and roads between continents (Lec2, RQ5 and RQ8); scholars who lost a career and found an art, and a court that lost a country (Lec3, RQ6, 7, 9, 10, 11). Lecture 3 is the heaviest, with five review questions, but its blocks are short and each ends with a Your Turn slide. The Pierian Spring in Lecture 1 holds the optional material (the Secret History, Marco Polo, Japan, Phags-pa). The "Coming next" slides (Lec1 AD, Lec2 w, Lec3 y) link the three decks and point to Chapter 14.
Two structural observations, neither requiring a new slide. First, Lecture 2's Your Turn for Review Question 8 comes after a long run of travel and exchange slides; students should be told in the notes (as they are) that Q8 can be answered through porcelain alone. Second, Lecture 3's account of the fall goes beyond Ebrey, so its Sources slide now names the Cambridge History chapters that carry it.
6. Individual background essay audits
Lecture 1, The Mongols Conquered China in Two Stages. Revised. Four acts on Review Questions 1–4 and a short Pierian Spring section. The revision corrects the page anchors, replaces "at first they did not try to hold territory" with the darughachi and Muqali evidence, adds the population, revenue and Dadu figures with sources, adds footnotes and expands the Corrections and Cautions. Status: draft for review.
Lecture 2, Ranks, Registers and Roads: How the Yuan Sorted Its People and Opened Eurasia. New. Two acts on Review Questions 5 and 8: the four labels in law and practice, hereditary households, the "ten grades," Ahmad and Phags-pa; the canal and the sea, Quanzhou, the two travelers, cobalt and Jingdezhen, the West Asian market, the David Vases and the exchange of knowledge. Status: draft for review.
Lecture 3, Scholars, Stages and the Fall of the Yuan. New. Five blocks on Review Questions 6, 7, 9, 10 and 11: loyalists, alternative paths and Zhao Mengfu; the examinations and quotas; zaju; literati painting and the Four Masters; succession feuds, paper money, the Yellow River, the Red Turbans and Zhu Yuanzhang. Status: draft for review.
All three essays follow the series format (central interpretation, story outline, acts keyed to review questions with textbook anchors, answer syntheses, Corrections and Cautions, footnotes and annotated reading) and use the permanent slide letters.

8. Deck issues, verification and fixes applied
Each row names the permanent slide letter, the issue, the verdict with the source that settled it, and the action taken. "Confirmed" means a reliable source supports the deck's version or the correction; "Ebrey supported" means the check upheld the textbook; "Not confirmed" means no reliable source settled it, so the deck keeps its cautious wording. The fixes have been applied to working copies of the three decks, pending Steven's approval before they are published. Every fix keeps the slide's letter and position, and no slide was added. The only visible-text change is the Phags-pa line on Lec1 V; the other changes are instructor notes, Sources slides and, on Lecture 1, source citations inside existing notes. The textbook's version is explained only in the notes, with a "Source beyond Ebrey" line, and the confirming works are listed on each deck's Sources slide under "Further reading beyond Ebrey." No visible "outside the textbook" tag exists in any Chapter 12 deck.
Lecture 1 · Mongol Conquest and State-Building (slides A–AJ)
Strong narrative in four acts with a Pierian Spring; the visible slides already corrected Ebrey on plunder, Dadu and the trebuchet stones. Verified correct: the 1211 campaign, Zhongdu 1215, Xia 1227, Kaifeng 1233, the pasture debate and revenue figures, Yao Shu and Cao Bin, Li Tan, the Yuan name, Xiangyang and Fancheng, Bayan, Hangzhou and Yashan.

Accurate and well sourced; every Chinese passage it translates was found in the Yuan shi. Verified correct: the 1290 census, the 1265 order, the law treatise, Ahmad, Phags-pa, the canal and sea routes, the Fuliang bureau and the dated vases.
| Slide | Issue | Verdict and source | Action |

| f | "The Han must not strike back"; Han forbidden to carry weapons, Han soldiers exempt. | CONFIRMED. Yuan shi ch. 105. | No change. |
| g | How rigid were the "four classes"? | Interpretation, not a contradiction. Ebrey (p. 203) gives the four grades; the slide keeps them and adds the debate (Meng Siming 1938; Funada 2005; Endicott-West 1989). | No change. |
| j | Ahmad, finance minister 1262–1282; Wang Zhu; Khubilai's verdict. | CONFIRMED. Yuan shi ch. 205: 王著殺之,誠是也. | No change. |

Audit conclusion
The Chapter 12 decks are the most carefully sourced in the course so far. They had already absorbed an outside audit, they translate their Chinese sources directly, and where Ebrey simplifies (plunder, Dadu, the trebuchet stones, the "ten grades," Tang blue-and-white) the visible slides already taught the better history. Every item that would contradict the textbook was checked against a reliable source before any change. The confirmed textbook slips are now recorded in instructor notes with their sources: the misprinted reign (Lec1 B), "only plundered" (Lec1 F), Dadu's date (Lec1 U), the "fine" (Lec2 f), the "new style" (Lec2 q), the two revival dates of 1313 and 1315 (Lec3 i), the "2 percent" (Lec3 j) and "Ni Can" (Lec3 r). The Phags-pa overclaim on Lec1 V was softened to "for official documents across his empire" (CHC 6, p. 605). The Sources slides now separate the textbook from further reading beyond Ebrey. Two textbook claims, Renzong as the first Mongol emperor to read Chinese and Guan Hanqing's play count, were not confirmed, and the decks keep their cautious wording. The README's open quotations and dates were all confirmed. The three essays teach the same history as the slides. The deck changes are in working copies and will not be published until Steven approves them.
