Kublai Khan, however, supported Baraq, a great-grandson of Chagatai. Baraq gained the loyalty of Mubarak Shah's army soon moved against him, exiling him that year. Later, Mubarak Shah supported Kaidu against Baraq in 1271, but soon felt compelled to defect to another enemy of Kaidu, the Ilkhan Abaqa.
