Гуюк
Oghul Qaimish, the widow of Güyük Khan, ruled as regent over the Mongol realm from 1249 to 1251. In 1250 the French diplomats André de Longjumeau, Guy de Longjumeau, and Jean de Carcassonne arrived at her court located along the Emil River (on the Kazakh-Chinese border), bearing gifts and representing their sovereign Louis IX of France, who desired a military alliance. Empress Qaimish viewed the gifts as tributary offerings and, in addition to gifts given in return, entrusted to Louis' diplomats, she sent the French monarch a letter demanding his submission as a vassal.
