Abstract
The Destruction of the Medieval Chinese Aristocracy, by Nicolas Tackett. Cambridge, Harvard University Asia Center, 2014. Harvard-Yenching Institute Monograph Series 93. xv, 281 pp. $49.95 US (cloth). The book under review is a substantive contribution to social history, historiography, human geography, and material culture in Tang China (618-906). It is an admirable application of gis (China Historical System) and social network analysis to sinology. The research undertaken by Tackett is remarkable, with the creation of a huge database derived from several thousands of excavated epitaphs recording the lives of men and women from the seventh to the tenth centuries. He used the gis to generate comparative charts plotting the transformation and migratory pathways of descendants of the medieval aristocracy that traced its origins to the first century. Checking the epigraphic evidence against digital biographies, anecdotal collections, and dynastic histories, he provides empirical data to confirm the research outcomes of two generations of Chinese, Japanese, and western scholarship on the Chinese medieval aristocracy. Tackett begins with the tomb epitaph of Ms. Lu, who hailed from the prestigious Fanyang (Beijing) clan and married into an eminent clan in Luoyang. Her son passed the highest level of examinations and her son-in-law became chief minister. In 880 when the Huang Chao (d. 884) rebels swept into the capitals of Luoyang and Chang'an, she perished along with four of her five children, who died without heirs. Only one son survived, and a nephew buried her with three epitaphs that form part of Tackett's epigraphic data. The extinction of the clans of her father, husband, and son-in-law mirrored the broader crisis of the medieval aristocracy and its total disappearance from the mass killings of the members. Chapter one presents the medieval aristocracy as a hierarchy of top-ranked, eminent, and famous-surname clans that survived several dynastic changes, on the strength of breeding, education, morality, public service and a strong social network sustained by endogamous marriages. The epitaph shows the individual's life passages as well as clan descent and social networks. The materiality of the epitaph (such as the length of the epitaph, calligraphy, and quality of tombstone) is indicative of clan hierarchy and differentiated wealth among the elites. Charts generated from plotting 6,255 epitaphs show that the top-ranked and eminent great clans moved into Chang'an and Luoyang while less distinguished clans relocated to peripheral regions. The next chapter uses geographic data to show that the capital elites were sharply distinct from the provincial elites. Based in the Chang'an/ Luoyang / surrounding region, the capital elites dominated key central government posts for a number of generations. The provincial elite spread in the provinces and only one or two generations held public office. Downward mobility is observed when certain capital elites transferred to the provinces for term appointments, while upward mobility can be seen where wealthy merchants, clergy, military, and other non-officeholder elite families moved into the capital region. …

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
