In the late thirteenth century the openness andreligious toleration of the Mongol Empire createdunique conditions which encouraged Europeanmissionaries to venture into Asia. The Franciscansand Dominicans who answered the call to evangelizein territories under Tartar dominion enjoyed suchsuccess by the early fourteenth century that thepapacy created archbishoprics and suffragan sees inCentral Asia and China, and entertained dreams ofnew Christian communities aligned with the RomanChurch. This paper focuses on a special set ofcircumstances which briefly encouraged thoseexpectations. Western missionaries to the Mongolsfound influential Christian women, the mothers andconsorts of rulers, at the courts of several khans.Because these Mongol queens played powerfulpolitical roles, their prayers and example mightencourage the conversion of their people and thosesubject to them. Faithful wives of pagan rulers, intimes long gone, had played a dynamic part in theconversion of husbands or sons, and of their realms,thus contributing to the spread of Christianity inEurope. Once again, at the close of the thirteenthcentury, hopes were voiced that pious women mightperform a similar task in Asia.
