海都一生曾做过两件轰轰烈烈的大事。其一，他恢复和扩大了窝阔台汗国；其二，他企图恢复祖先汗位。从前者来说，他挽救了濒临灭亡的窝阔台家族和汗国的命运，也使中亚的经济和政治得以维持半个世纪的和平与发展。从后者来说，海都因争夺汗位而对蒙古帝国的分裂负有一定责任，但绝非罪魁祸首。尽管他没有达到最终目的，但从其一生作为来看，他仍不失为一个有为的君主。 Hai Du have done two vigorous events throughout his life. First, he restored and expanded the Wo Koutai Khanate. Second, he attempted to restore his ancestral sweat bit. In the former case, he has saved the fate of the verge of the destruction of the family and Khanate of the Wokkai Islands and also enabled Central Asia’s economy and politics to maintain peace and development for half a century. From the latter, it is not the culprit, however, that the sea was responsible for the division of the Mongol Empire for sweat. Although he did not achieve his ultimate goal, but from the point of view of his life, he is still a promising monarch.
