The Rashīdī History 4.2.5

4.2.5

In this strife, the Chaghatai princess appears to have taken no part, but she suffered nevertheless, for in 1261 she was driven from Almaligh by Algu (a great-grandson of Chingiz), who had been nominated by Artukbuka to rule in her place, and to bring over the Chaghatai forces to assist him in his war with Kublai. Algu, however, betrayed his patron, who, abandoning Karakorum to his rival Kublai, marched against Almaligh, whence Algu had to fly for safety, first to Kashghar and Khotan, and finally to Samarkand. Artukbuka spent the winter of 1263 in Almaligh, devastating the district and putting to death many of Algu's followers. By these excesses he weakened his own army and resources to so great a degree, that he had to submit to Kublai and make peace with Algu, stipulating to retain for himself a portion only, of the eastern part of the Chaghatai Khanate. These transactions brought about not only a reconciliation between Algu and Organah, but a marriage. Both, however, died within a few months, and Artukbuka, having done homage to Kublai, by prostrating himself at the door of Kublai's tent, the latter remained supreme from Peking to Transoxiana, and acquired the title of Khakan. He was the "Great Kaan" of Marco Polo.
