Alagh Khan (Mongolian: Алаг хаан; Chinese: 阿剌克汗), born Bodi (Mongolian: Боди; Chinese: 博迪), was a khagan of the Northern Yuan dynasty, reigning from 1519 to 1547. Bodi Alagh Khan was Turbolad's eldest son and was handpicked by his grandfather Dayan Khan as his successor. However, after the death of Dayan Khan, Bars Bolud Jinong, Dayan Khan's third son, proclaimed himself as the great khan, claiming that Bodi Alagh Khan was too young and too inexperienced to maintain the large Mongol empire, and he was able to rally support from some Mongol populace who feared that after a century of fighting, the unification and prosperity finally achieved by Dayan Khan was to be lost and a more experience leader was needed.
