This article traces changing attitudes toward concubines across the Song and Yuan periods by examining how concubines are discussed in the genre of funerary inscriptions. It shows that the term “concubine” as used in the Song and Yuan encompassed women of many different statuses, from servant, to entertainer, to quasi-wife. It also shows that references, from servant, to entertainer, to quasi-wife. It also shows that references to concubines in funerary inscriptions across this period were becoming both more frequent and more respectful than in earlier eras. In particular, concubine mothers appear with increasingly frequency in funerary inscriptions of the Southern Song and Yuan. First appearing in the funerary biographies of their sons and daughters-in-law (where they serve as a vehicle for demonstrating the filial affections of the subject), in the late Song concubines begin to be acknowledge in the funerary biographies of their husbands, as mother of his children. The new attention to concubine mothers is matched by new attention to the disposition of the their children: the ideal of equal inheritance for all children is articulated with increasing force, even as the texts reveal that this ideal was often ignored in practice. In this new rhetoric about concubines and their children, we see reflections of the emerging ideal of family and lineage solidarity that was to characterize Chinese society in the late imperial period. The article concludes by suggesting that, in spite of funerary inscriptions’ rhetoric of “domestication,” the integration of concubines into family life was necessarily partial and tenuous. In Song and Yuan society, a society marked by fluidity of social status and intense competition among the elite, the flexibility provided by concubinage gave families an important competitive edge. Inscription rhetoric worked to disguise the very flexibility that made concubinage useful in this new social environment.
