A. Tom Grunfeld says that Tsongkhapa claimed ill health in his refusal to appear at the Ming court, while Rossabi adds that Tsongkhapa cited the "length and arduousness of the journey" to China as another reason not to make an appearance. This first request by the Ming was made in 1407, but the Ming court sent another embassy in 1413, this one led by the eunuch Hou Xian (; fl. 14031427), which was again refused by Tsongkhapa. Rossabi writes that Tsongkhapa did not want to entirely alienate the Ming court, so he sent his disciple Chosrje Shakya Yeshes to Nanjing in 1414 on his behalf, and upon his arrival in 1415 the Yongle Emperor bestowed upon him the title of "State Teacher"the same title earlier awarded the Phagmodrupa ruler of Tibet. The Xuande Emperor (r. 14251435) even granted this disciple Chosrje Shakya Yeshes the title of a "King" (). This title does not appear to have held any practical meaning, or to have given its holder any power, at Tsongkhapa's Ganden Monastery. Wylie notes that thislike the Karma Kargyucannot be seen as a reappointment of Mongol Yuan offices, since the Gelug school was created after the fall of the Yuan dynasty.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did the Ming first request Tsongkhapa to come to court?
1407
