In spite of the establishment of the Mongol rule in China in the thirteenth century, Chinese culture remained powerfully influential. The conquering Mongols and their Semu(Central and Western Asians) collaborators were inevitably influenced by the Chinese culture in various ways. Nevertheless, because of the existence of the conquest situation and the ethnic class system instituted by the Mongols to perpetuate the privileges of the conquering groups, the Mongols and Semu didn’t give up their ethnic identities and become because “sinicized”. However, in the existing epigraphs of Mongol and Semu women written by Chinese literati, one would look for in vain the trace of their original ethnic and cultural identies. These women appeared invariably in the images of ideal Confucian women. Upon reading these epigraphs, one wonders whether these texts provide accurate indications of the sinicization of there alien women and abandonment of their own cultures. This paper studies the epigraphical and biographical material of ten alien women. First, through this study and verification of their natal and husbands’ family backgrounds, if seeks to understand the extent to which these women were influenced by Chinese culture. Secondly, the images of these women depicted in epigraphs will be analyzed. Lastly, the socio-political background of the writers and inviters will be discussed in order to identify the motivations and limitations of their writing and understand the ways in which the women’s families interacted with various ethnic groups. Hopefully, the study of alien women’s epigraphs will bring into attention the textual limitations in the understanding of sinicization of the Mongol and Semu peoples in the Mongol-Yuan Period. An overestimation of the Chinese influence on these alien groups should be avoided.
