[Little is known of the way in which Chaghatai disposed of his kingdom at his death, and there appears to be no mention, anywhere, of his having followed the ancestral custom of his house in distributing it among his descendants. He is recorded to have left a numerous family, but to have been succeeded by a grandson, and a minor, named Qara Hülëgü, while his widow, Ebuskun, assumed the regency]
